CVE ID : CVE-2024-2961
Debian Bug : 1069191

Charles Fol discovered that the iconv() function in the GNU C library is
prone to a buffer overflow vulnerability when converting strings to the
ISO-2022-CN-EXT character set, which may lead to denial of service
(application crash) or the execution of arbitrary code.

For the oldstable distribution (bullseye), this problem has been fixed
in version 2.31-13+deb11u9.
