| Vector | AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
GNU C Library (glibc) versions 2.31 and earlier
Description
The issue is related to the iconv program in the GNU C Library. When invoked with multiple suffixes in the destination encoding along with the -c option, it enters an infinite loop when processing invalid multi-byte input sequences. This can lead to a denial of service. The vulnerability is associated with insufficient input validation, which can be exploited by a remote attacker to cause a denial of service when the iconv utility is called with the -c option.
Recommendations
For GNU C Library (glibc) versions 2.31 and earlier, consider avoiding the use of the -c option with multiple suffixes in the destination encoding to minimize the risk of exploitation. As a temporary workaround, restrict the use of the iconv utility until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
