Astra Linux – Vulnerability in glibc

The iconv function in the GNU C Library also known as glibc or libc6 version 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially leading to a denial of service...

Astra Linux – Vulnerability in glibc

The iconv function in the GNU C Library versions 2.39 and earlier may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set. This could potentially cause an application to crash or overwrite a neighboring variable...

CVE-2026-58082

The ISO-2022 encoding module used a stack buffer sized to MBLENMAX 6 bytes for intermediate character output. Some ISO-2022 variants can require up to 10 bytes per character, in which case conversions can trigger a stack buffer overflow of up to four bytes. An application that uses iconv3 to...

CVE-2026-58082

A stack-based buffer overflow exists in the iconv(3) library's ISO-2022 encoding module on FreeBSD . The module uses a stack buffer sized to MB_LEN_MAX (6 bytes) for intermediate character output, but certain ISO-2022 variants require up to 10 bytes per character, triggering a potential overflow ...

CVE-2026-29078

Lexbor is a web browser engine library. Prior to 2.7.0, the ISO‑2022‑JP encoder in Lexbor fails to reset the temporary size variable between iterations. The statement ctx-bufferused -= size with a stale size = 3 causes an integer underflow that wraps to SIZEMAX. Afterwards, memcpy is called with ...
