"According to the versions of the glibc packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

    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)

Tenable has extracted the preceding description block directly from the EulerOS glibc security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
