According to the versions of the glibc packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.(CVE-2021-3326)
A flaw was found in glibc. When processing input in the EUC-KR encoding, an invalid input sequence could cause glibc to read beyond the end of a buffer, resulting in a segmentation fault. The highest threat from this vulnerability is to system availability.(CVE-2019-25013)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
