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

The ISO-2022 encoding module in FreeBSD's iconv(3) allocates a 6-byte stack buffer (MB_LEN_MAX) but some variants require up to 10 bytes per character, causing up to a 4-byte stack overflow. Affects all supported FreeBSD versions; patched in stable/14 and stable/15 branches on 2026-06-30. No work...
