EulerOS Virtualization 2.15.0 : libarchive (EulerOS-SA-2026-4600)

high Nessus Plugin ID 377334

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

An issue was discovered in libarchive bsdtar before version 3.8.1 in function apply_substitution in file tar/subst.c when processing crafted -s substitution rules. This can cause unbounded memory allocation and lead to denial of service (Out-of-Memory crash).(CVE-2025-60753)

A flaw was identified in the RAR5 archive decompression logic of the libarchive library, specifically within the archive_read_data() processing path. When a specially crafted RAR5 archive is processed, the decompression routine may enter a state where internal logic prevents forward progress. This condition results in an infinite loop that continuously consumes CPU resources. Because the archive passes checksum validation and appears structurally valid, affected applications cannot detect the issue before processing. This can allow attackers to cause persistent denial-of-service conditions in services that automatically process archives.(CVE-2026-4111)

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

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

Solution

Update the affected libarchive packages.
