CVE-2021-43396 (GCVE-0-2021-43396)

Vulnerability from cvelistv5 – Published: 2021-11-04 19:52 – Updated: 2024-08-04 03:55

Summary

In iconvdata/iso-2022-jp-3.c in the GNU C Library (aka glibc) 2.34, remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. This may affect data integrity in certain iconv() use cases. NOTE: the vendor states "the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug.

Severity ?

No CVSS data available.
