EulerOS 2.0 SP12 : python3 (EulerOS-SA-2026-4527)

high Nessus Plugin ID 376733

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 :

 The Oracle Solaris Third Party Bulletin announces patches for one or more security vulnerabilities addressed in third party software that is included in Oracle Solaris distributions. Starting January 20, 2015, Third Party Bulletins are released on the same day when Oracle Critical Patch Updates are released.
 These bulletins will also be updated for the following two months after their release (i.e. the two months between the normal quarterly Critical Patch Update publication dates). In addition, Third Party Bulletins may also be updated for vulnerability issues deemed too critical to wait for the next monthly update.(CVE-2026-6879)

 unicodedata.normalize() can take excessive CPU time when processing specially crafted Unicode input containing long runs of combining characters with alternating Canonical Combining Class values.
 This affects all normalization forms.(CVE-2026-3276)

 The ftpcp() function in Lib/ftplib.py was not updated when CVE-2021-4189 was fixed. While makepasv() was patched to replace server-supplied PASV host addresses with the actual peer address (getpeername()[0]), ftpcp() still calls parse227() directly and passes the raw attacker-controllable IP address and port to target.sendport(). This patch is related to CVE-2021-4189.(CVE-2026-8328)

 When using the 'tarfile' module with a file opened in 'streaming mode' (mode='r|') the tarfile module did not properly handle EOF, making archive parsing take exponentially longer.(CVE-2026-11972)

 When using the 'configparser' module to write configuration files containing multi-line text values with carriage return characters (\r) the resulting file could be injected with unexpected keys and values if the attacker controls the written value.(CVE-2026-0864)

 In the Tarfile.extract() function, the filter parameter is not passed properly when extracting hardlinks.
 An affected system that extracts content from untrusted tar files could end up writing files with an unexpected uid/gid despite the user passing filter='data' to the extract() function.(CVE-2026-4360)

 When decompressing crafted zip files using the bzip/LZMA/Zstandard

 compressions, Python could use an attacker-controlled size to

 pre-allocate memory, possibly resulting in memory exhaustion.(CVE-2026-15310)

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.
