EulerOS 2.0 SP12 : libarchive (EulerOS-SA-2026-4413)

low Nessus Plugin ID 376684

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 signed integer overflow vulnerability was found in libarchive's ZIP writer. In the archive_write_zip_header function in archive_write_set_format_zip.c, when ZIP encryption is enabled and the entry file size is close to INT64_MAX, the addition of the encryption overhead to the entry size overflows int64_t, resulting in undefined behavior. This could lead to incorrect Zip64 extension decisions or potential memory corruption.(CVE-2026-16517)

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.
