This particular package contains the most important se...

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...

glibc: glibc: Information disclosure or denial of service via ungetwc function with specific wide character encodings

A flaw was found in glibc GNU C Library. When the ungetwc function is called on a file stream using wide characters with specific overlapping single-byte and multi-byte encodings, it may attempt to read data outside of its allocated buffer. This can lead to the unintentional disclosure of sensiti...

SUSE CVE-2026-6238

The deprecated functions nsprintrrf, nsprintrr and fpnquery in the GNU C Library version 2.0.1 to version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response,...

Amazon Linux 2 : glibc, --advisory ALAS2-2026-3272 (ALAS-2026-3272)

The version of glibc installed on the remote host is prior to 2.26-64. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3272 advisory. The iconv function in the GNU C Library versions 2.43 and earlier may crash due to an assertion failure when converting inputs from t...
