EulerOS Virtualization 2.10.0 : glibc (EulerOS-SA-2024-1378)

medium Nessus Plugin ID 192086

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

- A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the
_nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. (CVE-2023-4806)

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.

Solution

Update the affected glibc packages.
