 - The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. (CVE-2024-2961)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

 # emerge --sync # emerge --ask --oneshot --verbose >=sys-libs/glibc-2.38-r13
