EulerOS 2.0 SP8 : python2 (EulerOS-SA-2020-1295)

medium Nessus Plugin ID 134787

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the python2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- ** DISPUTED ** The Wave_read._read_fmt_chunk function in Lib/wave.py in Python through 3.6.4 does not ensure a nonzero channel value, which allows attackers to cause a denial of service (divide-by-zero and exception) via a crafted wav format audio file. NOTE:
the vendor disputes this issue because Python applications 'need to be prepared to handle a wide variety of exceptions.'(CVE-2017-18207)

- Python 2.7 through 2.7.17, 3.5 through 3.5.9, 3.6 through 3.6.10, 3.7 through 3.7.6, and 3.8 through 3.8.1 allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking.(CVE-2020-8492)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python2 packages.
