 Package : glibc 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.

 For the stable distribution (bookworm), this problem has been fixed in version 2.36-9+deb12u6.

 We recommend that you upgrade your glibc packages.

 For the detailed security status of glibc please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/glibc
