CVE-2021-20225 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 6.7 Medium |
A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-9490 | 7 Apache, Canonical, Debian and 4 more | 25 Http Server, Ubuntu Linux, Debian Linux and 22 more | 2023-11-07 | 7.5 High |
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. | ||||
CVE-2020-6851 | 5 Debian, Fedoraproject, Oracle and 2 more | 12 Debian Linux, Fedora, Georaster and 9 more | 2023-11-07 | 7.5 High |
OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation. | ||||
CVE-2020-27779 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 7.5 High |
A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-27749 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 6.7 Medium |
A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-25647 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 7.6 High |
A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-25632 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 8.2 High |
A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-14372 | 4 Fedoraproject, Gnu, Netapp and 1 more | 9 Fedora, Grub2, Cloud Backup and 6 more | 2023-11-07 | 7.5 High |
A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability. | ||||
CVE-2020-14311 | 4 Canonical, Gnu, Opensuse and 1 more | 7 Ubuntu Linux, Grub2, Leap and 4 more | 2023-11-07 | 6.0 Medium |
There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. | ||||
CVE-2020-14310 | 4 Canonical, Gnu, Opensuse and 1 more | 7 Ubuntu Linux, Grub2, Leap and 4 more | 2023-11-07 | 6.0 Medium |
There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. | ||||
CVE-2020-10711 | 5 Canonical, Debian, Linux and 2 more | 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more | 2023-11-07 | 5.9 Medium |
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service. | ||||
CVE-2019-9959 | 4 Debian, Fedoraproject, Freedesktop and 1 more | 7 Debian Linux, Fedora, Poppler and 4 more | 2023-11-07 | 6.5 Medium |
The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the heap, with a size controlled by an attacker, as demonstrated by pdftocairo. | ||||
CVE-2019-9903 | 5 Canonical, Debian, Fedoraproject and 2 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2023-11-07 | 6.5 Medium |
PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0 mishandles dict marking, leading to stack consumption in the function Dict::find() located at Dict.cc, which can (for example) be triggered by passing a crafted pdf file to the pdfunite binary. | ||||
CVE-2019-9636 | 7 Canonical, Debian, Fedoraproject and 4 more | 16 Ubuntu Linux, Debian Linux, Fedora and 13 more | 2023-11-07 | 9.8 Critical |
Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. | ||||
CVE-2019-7310 | 5 Canonical, Debian, Fedoraproject and 2 more | 11 Ubuntu Linux, Debian Linux, Fedora and 8 more | 2023-11-07 | 7.8 High |
In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo. | ||||
CVE-2019-7222 | 7 Canonical, Debian, Fedoraproject and 4 more | 18 Ubuntu Linux, Debian Linux, Fedora and 15 more | 2023-11-07 | 5.5 Medium |

CVE-2019-7221 | 7 Canonical, Debian, Fedoraproject and 4 more | 15 Ubuntu Linux, Debian Linux, Fedora and 12 more | 2023-11-07 | N/A |
The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. | ||||
CVE-2019-6974 | 5 Canonical, Debian, F5 and 2 more | 24 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 21 more | 2023-11-07 | 8.1 High |
In the Linux kernel before 4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandles reference counting because of a race condition, leading to a use-after-free. | ||||
CVE-2019-6454 | 8 Canonical, Debian, Fedoraproject and 5 more | 22 Ubuntu Linux, Debian Linux, Fedora and 19 more | 2023-11-07 | 5.5 Medium |
An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic). | ||||
CVE-2019-6116 | 6 Artifex, Canonical, Debian and 3 more | 11 Ghostscript, Ubuntu Linux, Debian Linux and 8 more | 2023-11-07 | 7.8 High |
In Artifex Ghostscript through 9.26, ephemeral or transient procedures can allow access to system operators, leading to remote code execution. |
