CVE-2021-3595 4 Debian, Fedoraproject, Libslirp Project and 1 more 4 Debian Linux, Fedora, Libslirp and 1 more 2023-11-07 3.8 Low
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the size of the 'tftp_t' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.
CVE-2021-3594 4 Debian, Fedoraproject, Libslirp Project and 1 more 4 Debian Linux, Fedora, Libslirp and 1 more 2023-11-07 3.8 Low
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp_input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.
CVE-2021-3593 4 Debian, Fedoraproject, Libslirp Project and 1 more 4 Debian Linux, Fedora, Libslirp and 1 more 2023-11-07 3.8 Low
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.
CVE-2021-3592 4 Debian, Fedoraproject, Libslirp Project and 1 more 4 Debian Linux, Fedora, Libslirp and 1 more 2023-11-07 3.8 Low
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the bootp_input() function and could occur while processing a udp packet that is smaller than the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.
CVE-2020-29130 3 Debian, Fedoraproject, Libslirp Project 3 Debian Linux, Fedora, Libslirp 2023-11-07 4.3 Medium
slirp.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
CVE-2020-29129 3 Debian, Fedoraproject, Libslirp Project 3 Debian Linux, Fedora, Libslirp 2023-11-07 4.3 Medium
ncsi.c in libslirp through 4.3.1 has a buffer over-read because it tries to read a certain amount of header data even if that exceeds the total packet length.
CVE-2020-1983 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 6.5 Medium
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service.
CVE-2020-10756 5 Canonical, Debian, Libslirp Project and 2 more 6 Ubuntu Linux, Debian Linux, Libslirp and 3 more 2023-11-07 6.5 Medium
An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1.
CVE-2019-14378 1 Libslirp Project 1 Libslirp 2023-11-07 N/A
ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it mishandles a case involving the first fragment.
CVE-2020-7039 4 Debian, Libslirp Project, Opensuse and 1 more 4 Debian Linux, Libslirp, Leap and 1 more 2021-02-14 5.6 Medium
tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.
CVE-2020-8608 3 Debian, Libslirp Project, Opensuse 3 Debian Linux, Libslirp, Leap 2021-02-14 5.6 Medium
In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code.
CVE-2019-15890 2 Libslirp Project, Qemu 2 Libslirp, Qemu 2020-03-11 7.5 High
libslirp 4.0.0, as used in QEMU 4.1.0, has a use-after-free in ip_reass in ip_input.c.
CVE-2020-7211 3 Libslirp Project, Microsoft, Qemu 3 Libslirp, Windows, Qemu 2020-01-23 7.5 High
tftp.c in libslirp 4.1.0, as used in QEMU 4.2.0, does not prevent ..\ directory traversal on Windows.
