**Name of the Vulnerable Software and Affected Versions** GNU C Library (aka glibc or libc6) versions 2.30 through 2.32 **Description** The iconv function in the GNU C Library, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. **Recommendations** For versions 2.30 through 2.32, consider updating to a version where this issue is fixed, as the current version may abort the program when encountering irreversible characters during UCS4 text conversion. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
