EulerOS 2.0 SP8 : libarchive (EulerOS-SA-2023-1322)

critical Nessus Plugin ID 171171

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - In libarchive before 3.6.2, the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference.
 NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: 'In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution.' (CVE-2022-36227)

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 libarchive packages.
