Astra Linux – Vulnerability in Python 3.11

The import hook in CPython that handles legacy .pyc files SourcelessFileLoader is incorrectly handled in FileLoader a base class, and therefore does not use io.opencode to read the .pyc files. As a result, the sys.audit handlers for this audit event do not trigger...

Astra Linux – Vulnerability in Python 3.11

The email module, specifically the “BytesGenerator” class, did not properly quote newlines for email headers when serializing an email message. This issue occurs only when using “LiteralHeader” to write headers that do not follow email folding rules. The new behavior will reject incorrectly folde...

Astra Linux – Vulnerability in Python 3.11

When an Expat parser with a registered ElementDeclHandler parses an inline document type definition containing a deeply nested content model, a C stack overflow occurs...

Astra Linux – Vulnerability in Python 3.11

User-controlled header names and values containing newlines can allow for the injection of HTTP headers...

Astra Linux – Vulnerability in Python 3.11

User-controlled data URLs parsed by urllib.request.DataHandler allow injecting headers through newlines in the data URL’s media type...

Astra Linux – Vulnerability in Python 3.11

When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially leading to Out-of-Memory errors or other types of...

Astra Linux – Vulnerability in python-cryptography

Cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.5, the publickeyfromnumbers or EllipticCurvePublicNumbers.publickey, EllipticCurvePublicNumbers.publickey, loadderpublickey, and loadpempublickey functions did not verify...

Astra Linux – Vulnerability in Python 3.11

The imaplib module, when a user-controlled command is passed to it, can have additional commands injected using newlines. Mitigation rejects commands that contain control characters...

Astra Linux – Vulnerability in python-urllib3

urllib3 is a HTTP client library for Python. The streaming API of urllib3 is designed for efficiently handling large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP...

Astra Linux – Vulnerability in Python 3.11

When constructing nested elements using XMLDom.minidom methods like appendChild, which rely on clearidcache, the algorithm has a quadratic complexity. This can affect the availability of documents when they are constructed with excessively nested structures...

Astra Linux – Vulnerability in Python 3.11

The ‘zipfile’ module does not check the validity of the offset value specified in the ZIP64 End of Central Directory EOCD Locator record. Instead, the ZIP64 EOCD record is assumed to be the previous record in the ZIP archive. This behavior could be exploited to create ZIP archives that are...

Astra Linux – Vulnerability in Python-APT

Dereferencing a NULL pointer in TagSection.keys in Python-apt on APT-based Linux systems allows a local attacker to cause a denial of service process crash through a crafted deb822 file containing malformed non-UTF-8 keys...

Astra Linux – Vulnerability in Python 3.11

DISPUTED: The project has clarified that the documentation was incorrect, and that pkgutil.getdata has the same security model as open. The documentation has been updated to clarify this point. There is no vulnerability in the function if the intended security model is followed. pkgutil.getdata d...

Astra Linux – Vulnerability in Python 3.11

The webbrowser.open API accepts URLs with leading hyphens, which can be treated as command-line options for certain web browsers. However, the new behavior disallows the use of leading hyphens. It is recommended that users sanitize URLs before passing them to webbrowser.open...

Astra Linux – Vulnerability in Python 3.11

When folding a long comment within an email header that contains only printable characters, the parentheses will not be preserved. This can be exploited to inject headers into email messages where the addresses are controlled by users and not sanitized...

Astra Linux – Vulnerability in Python 3.11

If the value passed to os.path.expandvars is controlled by the user, there is a possibility of performance degradation when expanding environment variables...

Astra Linux – Vulnerability in Python 3.11

The “tarfile” module will still apply normalization of AREGTYPE \x00 blocks to DIRTYPE, even when processing multi-block members such as GNUTYPELONGNAME or GNUTYPELONGLINK. This could lead to a crafted tar archive being misinterpreted by the tarfile module compared to other implementations...

Astra Linux – Vulnerability in python-urllib3

urllib3 is a user-friendly HTTP client library for Python. Prior to version 2.5.0, it was possible to disable redirections for all requests by instantiating a PoolManager and specifying retries in a way that disables redirections. By default, requests and botocore users are not affected. An...

Astra Linux – Vulnerability in Python 3.11

When using http.cookies.Morsel, user-controlled cookie values and parameters may allow the injection of HTTP headers into messages. The patch rejects all control characters within cookie names, values, and parameters...

Astra Linux – Vulnerability in pyasn1

pyasn1 is a generic ASN.1 library for Python. Prior to version 0.6.3, the pyasn1 library was vulnerable to a Denial of Service DoS attack caused by uncontrolled recursion during the decoding of ASN.1 data with deeply nested structures. An attacker could provide a crafted payload containing...
