| CVE-2023-31130 | 3 C-ares Project, Debian, Fedoraproject | 3 C-ares, Debian Linux, Fedora | 2024-06-10 | 6.4 Medium |
| c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1. | ||||
| CVE-2023-34351 | 2024-02-14 | 7.5 High | ||
| Buffer underflow in some Intel(R) PCM software before version 202307 may allow an unauthenticated user to potentially enable denial of service via network access. | ||||
| CVE-2023-48230 | 1 Capnproto | 1 Capnproto | 2023-11-29 | 9.8 Critical |
| Cap'n Proto is a data interchange format and capability-based RPC system. In versions 1.0 and 1.0.1, when using the KJ HTTP library with WebSocket compression enabled, a buffer underrun can be caused by a remote peer. The underrun always writes a constant value that is not attacker-controlled, likely resulting in a crash, enabling a remote denial-of-service attack. Most Cap'n Proto and KJ users are unlikely to have this functionality enabled and so unlikely to be affected. Maintainers suspect only the Cloudflare Workers Runtime is affected. If KJ HTTP is used with WebSocket compression enabled, a malicious peer may be able to cause a buffer underrun on a heap-allocated buffer. KJ HTTP is an optional library bundled with Cap'n Proto, but is not directly used by Cap'n Proto. WebSocket compression is disabled by default. It must be enabled via a setting passed to the KJ HTTP library via `HttpClientSettings` or `HttpServerSettings`. The bytes written out-of-bounds are always a specific constant 4-byte string `{ 0x00, 0x00, 0xFF, 0xFF }`. Because this string is not controlled by the attacker, maintainers believe it is unlikely that remote code execution is possible. However, it cannot be ruled out. This functionality first appeared in Cap'n Proto 1.0. Previous versions are not affected. This issue is fixed in Cap'n Proto 1.0.1.1. | ||||
| CVE-2022-20683 | 1 Cisco | 1 Ios Xe | 2023-11-07 | 8.6 High |
| A vulnerability in the Application Visibility and Control (AVC-FNF) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient packet verification for traffic inspected by the AVC feature. An attacker could exploit this vulnerability by sending crafted packets from the wired network to a wireless client, resulting in the crafted packets being processed by the wireless controller. A successful exploit could allow the attacker to cause a crash and reload of the affected device, resulting in a DoS condition. | ||||
| CVE-2021-38575 | 2 Insyde, Tianocore | 2 Kernel, Edk2 | 2023-11-07 | 8.1 High |
| NetworkPkg/IScsiDxe has remotely exploitable buffer overflows. | ||||
| CVE-2018-5388 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2023-11-07 | N/A |
| In stroke_socket.c in strongSwan before 5.6.3, a missing packet length check could allow a buffer underflow, which may lead to resource exhaustion and denial of service while reading from the socket. | ||||
| CVE-2021-36064 | 2 Adobe, Debian | 2 Xmp Toolkit Software Development Kit, Debian Linux | 2023-10-20 | 7.8 High |
| XMP Toolkit version 2020.1 (and earlier) is affected by a Buffer Underflow vulnerability which could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. | ||||
| CVE-2023-32614 | 1 Accusoft | 1 Imagegear | 2023-09-26 | 9.8 Critical |
| A heap-based buffer overflow vulnerability exists in the create_png_object functionality of Accusoft ImageGear 20.1. A specially crafted malformed file can lead to memory corruption. An attacker can provide a malicious file to trigger this vulnerability. | ||||
| CVE-2021-38578 | 2 Insyde, Tianocore | 2 Kernel, Edk2 | 2023-08-02 | 9.8 Critical |
| Existing CommBuffer checks in SmmEntryPoint will not catch underflow when computing BufferSize. | ||||
| CVE-2022-33896 | 1 Hancom | 1 Hancom Office 2020 | 2022-10-11 | 7.8 High |
| A buffer underflow vulnerability exists in the way Hword of Hancom Office 2020 version 11.0.0.5357 parses XML-based office files. A specially-crafted malformed file can cause memory corruption by using memory before buffer start, which can lead to code execution. A victim would need to access a malicious file to trigger this vulnerability. | ||||
| CVE-2018-15361 | 1 Uvnc | 1 Ultravnc | 2020-06-10 | N/A |
| UltraVNC revision 1198 has a buffer underflow vulnerability in VNC client code, which can potentially result in code execution. This attack appears to be exploitable via network connectivity. This vulnerability has been fixed in revision 1199. | ||||
