EulerOS 2.0 SP12 : libarchive (EulerOS-SA-2026-3274)

high Nessus Plugin ID 343746

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 :

 A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.(CVE-2026-14164)

Tenable has extracted the preceding description block directly from the EulerOS libarchive security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libarchive packages.
