EulerOS Virtualization 2.13.0 : python3 (EulerOS-SA-2025-2614)

low Nessus Plugin ID 281582

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 During an address list folding when a separating comma ends up on a folded line and that line is to be unicode-encoded then the separator itself is also unicode-encoded. Expected behavior is that the separating comma remains a plan comma. This can result in the address header being misinterpreted by some mail servers.(CVE-2025-1795)

 There is an issue in CPython when using `bytes.decode('unicode_escape', error='ignore|replace')`. If you are not using the 'unicode_escape' encoding or an error handler your usage is not affected. To work-around this issue you may stop using the error= handler and instead wrap the bytes.decode() call in a try-except catching the DecodeError.(CVE-2025-4516)

 The html.parser.HTMLParser class had worse-case quadratic complexity when processing certain crafted malformed inputs potentially leading to amplified denial-of-service.(CVE-2025-6069)

 There is a defect in the CPython 'tarfile' module affecting the 'TarFile' extraction and entry enumeration APIs. The tar implementation would process tar archives with negative offsets without error, resulting in an infinite loop and deadlock during the parsing of maliciously crafted tar archives. This vulnerability can be mitigated by including the following patch after importing the 'tarfile' module:

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