CVE Vulnerability Catalog

Git is a fast, scalable, distributed revision control system. When cloning a repository Git knows to optionally fetch a bundle advertised by the remote server, which allows the server-side to offload.

A divide-by-zero error was discovered in py-lmdb 0.97 in the mdb_env_open2 function when mdb_env_read_header obtains a zero value for a certain size field. This issue can be triggered by supplying a crafted data.mdb file.

libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. It can detect an invalid field and return error. Unfortunately, when doing so it also invokes `free()` on a 4 byte local stack buffer. Most modern malloc implementations detect this error and immediately abort.

Git defines a line-based protocol used to exchange information between Git and Git credential helpers. Some ecosystems (most likely those using this protocol) may be vulnerable to attacks related to this protocol.

The faraday-http-cache library stores cached responses in JSON format by default and reads them back using JSON.load, which honors the json_class key and calls json_create on the named class. Response headers are stored verbatim in the cache entry, so a malicious origin server can return a response with a json_class key leading to unsafe deserialization.

This is a residual of GHSA-g5vv-9gxw-82hx / CVE-2026-87819. The 3.1.60 fix made Actor._from_string regex-free, but parse_actor_and_date still runs _re_actor_epoch on the same author/committer/tagger line one step earlier. That pattern backtracks quadratically when the trailing epo...

GitPython's config-name validator only neutralizes CR/LF/NUL for the "option" label; it does not reject =, #, ;, [, ], or whitespace in an option name. write_section writes the option name verbatim into the config file, so an option name such as sshCommand = touch <cmd> can inject configuration.

GitPython spent 2022-2026 rolling out two reusable guards method-by-method: Git.check_unsafe_protocols(url) (raises UnsafeProtocolError for <transport>:: remote-helper URLs) and Git.check_unsafe_options(...) (raises UnsafeOptionError for denylisted options). The description indicates the rollout did not cover all code paths.

Multiple cases were found in aiohttp where excessive or unbounded memory use, or excessive CPU consumption, can be triggered by attacker-controlled requests. An attacker could cause resource exhaustion through specially crafted requests.

A call to the token endpoint with a grant type of urn:ietf:params:oauth:grant-type:device_code and a bogus device_code can obtain a bearer token as long as a valid client ID enabled for the device workflow is known. This violates RFC 8628.

Pillow wheels from 11.1.0 onward bundle a libopenjp2 containing a heap-buffer-overflow write that is fixed upstream on master but has never appeared in an OpenJPEG release. Because the wheel bundles its own copy, a patched host library does not protect against the issue.

The description of this report does not contain sufficient technical information about the vulnerability — it only includes a note about the reporting method and references to files that were not attached. The nature and scope of the issue cannot be determined from it.

In GitPython, Remote.pull() forwards its positional refspec argument directly to the git pull child process while its unsafe-option guard inspects only keyword arguments. An application that passes attacker-influenced data as the refspec (e.g., a user-supplied branch name) may allow injection of unsafe options.

In Pillow's libtiff encoder (PyImaging_LibTiffEncoderNew in src/encode.c), crafted TIFF tags can cause memory disclosure and a segfault. The issue occurs when creating the LibTiff encoder.

The vulnerability occurs when an application uses OAuth2::Client and the authorization server returns a redirect with a Location header in the form of a protocol-relative URI. In this case, OAuth2::Client#request may incorrectly resolve the redirect.

The wheels of pyca/cryptography include a statically linked copy of OpenSSL. The versions of OpenSSL included in wheels prior to cryptograph 48.01 are vulnerable to a security issue.

A vulnerability in the libtiff library related to handling the SamplesPerPixel tag allows an attacker to cause a denial of service (DoS). Package updates are available for Amazon Linux 2023 that fix this issue.

node-tar to pełnoprawne narzędzie Tar dla Node.js. Przed wersją 7.5.11, tar (npm) może być oszukany w celu utworzenia symlinków wskazujących poza katalog ekstrakcji, co umożliwia nadpisywanie plików poza bieżącym katalogiem roboczym.

Several vulnerabilities (two rated critical under CVSSv3) have been discovered and fixed in the upstream libheif dependency. They can lead to remote code execution (RCE) on glibc-based Linux under certain conditions.

A rogue MySQL server (or a man-in-the-middle) can force mysql2 to send credentials in plaintext by requesting an auth switch to mysql_clear_password. The driver complies without verifying that TLS is active.
