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

  - The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when     processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in     degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
    (CVE-2021-27645)

  - A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory     corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and     size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and     escalate their privileges on the system. (CVE-2021-3999)

  - The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc)     through 2.34 copies its path argument on the stack without validating its length, which may result in a     buffer overflow, potentially resulting in a denial of service or (if an application is not built with a     stack protector enabled) arbitrary code execution. (CVE-2022-23218)

  - The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc)     through 2.34 copies its hostname argument on the stack without validating its length, which may result in     a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a     stack protector enabled) arbitrary code execution. (CVE-2022-23219)

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.
