CVE-2026-58081
A flaw was found in iconv. Several encoding modules, including HZ, UTF-7, VIQR, and ZW, did not properly validate the size of the provided output buffer before writing converted characters. This oversight could allow an application using iconv to convert untrusted input with one of the affected...
Astra Linux – Vulnerability in glibc
The iconv program in the GNU C Library also known as glibc or libc6 version 2.31 and earlier, when invoked with multiple suffixes in the destination encoding TRANSLATE or IGNORE along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, resulting in a...
Astra Linux – Vulnerability in zvbi
A vulnerability was discovered in libzvbi up to version 0.2.43. It has been classified as a problematic issue. The affected function is vbistrndupiconvucs2 in the file src/conv.c. Manipulating the srclength argument leads to an uninitialized pointer. This vulnerability can be exploited remotely...
