CVE-2024-6923

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.

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.

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces.

Security Fix(es):

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)

There is a HIGH severity vulnerability affecting the CPython "zipfile" module affecting "zipfile.Path". Note that the more common API "zipfile.ZipFile" class is unaffected.

When iterating over names of entries in a zip archive (for example, methods of "zipfile.Path" like "namelist()", "iterdir()", 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.(CVE-2024-8088)

Python 3.12 is an accessible, high-level, dynamically typed, interpreted programming language, designed with an emphasis on code readability. It includes an extensive standard library, and has a vast ecosystem of third-party libraries. The python3.12 package provides the "python3.12" executable: the reference interpreter for the Python language, version 3. The majority of its standard library is provided in the python3.12-libs package, which should be installed automatically along with python3.12. The remaining parts of the Python standard library are broken out into the python3.12-tkinter and python3.12-test packages, which may need to be installed separately. Documentation for Python is provided in the python3.12-docs package. Packages containing additional libraries for Python are generally named with the "python3.12-" prefix.

A defect was discovered in the Python “ssl” module where there is a memory race condition with the ssl.SSLContext methods “cert_store_stats()” and “get_ca_certs()”. The race condition can be triggered if the methods are called at the same time as certificates are loaded into the SSLContext, such as during the TLS handshake with a certificate directory configured. (CVE-2024-0397) 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. (CVE-2024-4032) 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) When iterating over names of entries in a zip archive (for example, methods of "zipfile.Path" like "namelist()", "iterdir()", 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. (CVE-2024-8088) Regular expressions that allowed excessive backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar archives. (CVE-2024-6232) 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) Urlparse insufficient validation leads to open redirect. (CVE-2015-2104) 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)
