CVE Vulnerability Catalog

A vulnerability was found in systemd where a service using the DynamicUser property can create a SUID/SGID binary that remains executable with the transient service UID/GID even after the service terminates. A local attacker could exploit this to access resources owned by a potentially different UID/GID.

The KeyTrap vulnerability in the DNSSEC protocol allows a remote attacker to cause a Denial of Service (DoS) by sending DNSSEC responses containing many DNSKEY and RRSIG records. This leads to excessive CPU consumption on the DNS server, potentially causing overload.

A vulnerability in Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The multiprocessing library with the forkserver start method permits pickle deserialization from any user on the same local network of the machine.

An issue was discovered in py-lmdb 0.97 where mdb_node_del does not validate a memmove in the case of an unexpected node->mn_hi, leading to an invalid write operation. This occurs when accessing a data.mdb file supplied by an attacker.

A vulnerability in the virtio-gpu module of the Linux kernel involves an incorrect overflow check when allocating 2D images. This flaw can lead to a buffer overflow, potentially enabling privilege escalation or system crash.

The filepath package in Go does not recognize paths with a \??\ prefix as special. On Windows, a path starting with \??\ is equivalent to a path starting with \\?\ and can be used to access arbitrary system locations.

A vulnerability in Go's HTTP/2 implementation allows a malicious client to rapidly create and reset requests, causing excessive server resource consumption. Although the number of concurrent streams is limited by MaxConcurrentStreams, resetting requests enables the attacker to continuously send new requests.

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.

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.

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.

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.

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.

@tiptap/core contains two quadratic regular-expression denial-of-service paths in its default Markdown attribute parsers. Pandoc-style block attributes use two unanchored greedy expressions that rescan repeated __QUOTED_0 prefixes. Inline shortcode attributes use another unanchored expression, which can lead to resource exhaustion.

Dalli's meta protocol request formatter writes some numeric arguments into memcached commands without converting them to integers. If an application passes an attacker-controlled String to one of these arguments, CRLF sequences in it are sent to memcached as additional commands on the same connection.

A memory-related vulnerability has been discovered and fixed in the librsvg dependency. Under certain runtime-specific conditions, it can lead to possible remote code execution (RCE) on glibc-based Linux.

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.

n8n to platforma automatyzacji procesów roboczych typu open source. Przed wersjami 2.10.1, 2.9.3 i 1.123.22, uwierzytelniony użytkownik z uprawnieniami do tworzenia lub modyfikowania procesów roboczych mógł wykorzystać węzeł Python Code do ucieczki z piaskownicy.

n8n to platforma automatyzacji procesów roboczych typu open source. Przed wersjami 1.123.12 i 2.4.0, podczas przetwarzania przesłanych plików i ich transferu do zdalnych serwerów za pomocą węzła SSH, brak walidacji metadanych może prowadzić do zapisywania plików w niezamierzonych lokalizacjach.

When addressparser finds no address by its strict reading, it falls back to pulling one out of the free text with /\s*\b[^@\s]+@[^\s]+\b\s*/. That pattern backtracks quadratically, causing high resource consumption when processing a single header.
