glibc: glibc: Heap Buffer Overflow in `scanf` with `%mc` format specifier and large width

A flaw was found in glibc GNU C Library. This vulnerability occurs when an application uses the scanf family of functions with a %mc format specifier, which is used for dynamically allocating memory for character input, and provides an explicit width greater than 1024. This specific combination c...

coreutils: Heap Buffer Under-Read in GNU Coreutils sort via Key Specification

A flaw was found in GNU Coreutils. The sort utility's begfield function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitiv...

CVE-2026-41992

GNU gzip contains a global buffer overflow vulnerability in the LZH decompression logic caused by improper reuse of shared global state between different decompression formats within a single execution. GNU gzip maintains a global array that is shared across the LZ77, LZW, and LZH decompression...

CVE-2026-41991

GNU gzip contains a vulnerability in the gzexe utility related to insecure temporary file handling. When the mktemp utility is not available in the user’s PATH, gzexe falls back to constructing a temporary file path based solely on the process ID PID. This predictable filename is created without...

gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...

CVE-2026-41991

CVE-2026-41991 affects GNU gzip’s gzexe utility, where insecure temporary file handling creates a TOCTOU vulnerability. If mktemp is unavailable in PATH, gzexe constructs a PID-based temporary path without exclusive access or existence checks. A local attacker can pre-create the predicted path as...
