EUVD-2026-62349

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 Stack based buffer overflow in iconv(3)

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-2026-58081

A heap-based buffer overflow exists in the iconv(3) library because several encoding modules, specifically HZ, UTF-7, VIQR, and ZW , fail to validate the size of caller-supplied output buffers before writing converted characters. Applications processing untrusted input through these encodings are...
