[CVE-2024-7592] Quadratic complexity parsing cookies with backslashes

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-2024-8088] Infinite loop when iterating over zip archive entry names

There is a HIGH severity vulnerability affecting the CPython "zipfile"
module.

When iterating over names of entries in a zip archive (for example, methods
of "zipfile.ZipFile" like "namelist()", "iterdir()", "extractall()", etc)
the process can be put into an infinite loop with a maliciously crafted
zip archive. This defect applies when reading only metadata or extracting
the contents of the zip archive. Programs that are not handling
user-controlled zip archives are not affected.
