Amazon Linux 2 Security Advisory: ALAS-2025-2754
Advisory Release Date: 2025-02-12 23:17 Pacific
Advisory Updated Date: 2025-02-25 10:30 Pacific
Severity: Medium
Issue Overview:

The urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts (`[]`), allowing hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially enabled SSRF if a URL is processed by more than one URL parser. (CVE-2024-11168)

There is a MEDIUM severity vulnerability affecting CPython.

The
email module didn't properly quote newlines for email headers when
serializing an email message allowing for header injection when an email
is 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 in
the cookie value, the parser would use an algorithm with quadratic
complexity, resulting in excess CPU resources being used while parsing the
value. (CVE-2024-7592)
