EulerOS 2.0 SP15 : python3 (EulerOS-SA-2026-3794)

high Nessus Plugin ID 346781

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the python3 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash the process when processing untrusted data.(CVE-2026-9669)

 tarfile.data_filter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall() to write files outside the destination directory, subject to the permissions of the extracting process.(CVE-2026-7774)

Tenable has extracted the preceding description block directly from the EulerOS python3 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 python3 packages.
