EulerOS 2.0 SP13 : python3 (EulerOS-SA-2026-1292)

medium Nessus Plugin ID 301571

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 :

 If the value passed to os.path.expandvars() is user-controlled a performance degradation is possible when expanding environment variables.(CVE-2025-6075)

 When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially causing OOM or other DoS.(CVE-2025-13836)

 When building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency on _clear_id_cache() the algorithm is quadratic. Availability can be impacted when building excessively nested documents.(CVE-2025-12084)

 The 'zipfile' module would not check the validity of the ZIP64 End of Central Directory (EOCD) Locator record offset value would not be used to locate the ZIP64 EOCD record, instead the ZIP64 EOCD record would be assumed to be the previous record in the ZIP archive. This could be abused to create ZIP archives that are handled differently by the 'zipfile' module compared to other ZIP implementations.Remediation maintains this behavior, but checks that the offset specified in the ZIP64 EOCD Locator record matches the expected value.(CVE-2025-8291)

 CPython 3.9 and earlier doesn't disallow configuring an empty list ('[]') for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured).(CVE-2024-5642)

 When loading a plist file, the plistlib module reads data in size specified by the file itself, meaning a malicious file can cause OOM and DoS issues(CVE-2025-13837)

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.
