EulerOS Virtualization 2.9.0 : zlib (EulerOS-SA-2023-1241)

critical Nessus Plugin ID 169987

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference). (CVE-2022-37434)

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 zlib packages.
