Amazon Linux 2023 : python3, python3-devel, python3-idle (ALAS2023-2024-790)

critical Nessus Plugin ID 213054

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-790 advisory.

 The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python. (CVE-2023-27043)

 The ipaddress module contained incorrect information about whether certain IPv4 and IPv6 addresses were designated as globally reachable or private. This affected the is_private and is_global properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and ipaddress.IPv6Network classes, where values wouldn't be returned in accordance with the latest information from the IANA Special-Purpose Address Registries.

 CPython 3.12.4 and 3.13.0a6 contain updated information from these registries and thus have the intended behavior. (CVE-2024-4032)

 There is a MEDIUM severity vulnerability affecting CPython.





 Regular expressions that allowed excessive backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar archives. (CVE-2024-6232)

 There is a MEDIUM severity vulnerability affecting CPython.

 Theemail module didn't properly quote newlines for email headers whenserializing an email message allowing for header injection when an emailis serialized. (CVE-2024-6923)

 There is a LOW severity vulnerability affecting CPython, specifically the'http.cookies' standard library module.

 When parsing cookies that contained backslashes for quoted characters inthe cookie value, the parser would use an algorithm with quadraticcomplexity, resulting in excess CPU resources being used while parsing thevalue. (CVE-2024-7592)

 There is a severity vulnerability affecting the CPython zipfilemodule.

 When iterating over names of entries in a zip archive (for example, methodsof zipfile.ZipFile like namelist(), iterdir(), extractall(), etc)the process can be put into an infinite loop with a maliciously craftedzip archive. This defect applies when reading only metadata or extractingthe contents of the zip archive. Programs that are not handlinguser-controlled zip archives are not affected.
 (CVE-2024-8088)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'dnf update python3.9 --releasever 2023.6.20241212' to update your system.
