CVE Vulnerability Catalog

A heap buffer overflow vulnerability was discovered in Perl. Affected versions include release branches 5.34, 5.36, 5.38, and 5.40, as well as development versions from 5.33.1 through 5.41.10. When non-ASCII bytes are present in the left-hand side of the `tr` operator, `S_do_trans_invmap` can overflow the buffer.

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.

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.

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.

@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.

In applications using OAuth::Consumer to request OAuth 1.0 tokens, the token request helper follows 300..399 redirects returned by the OAuth server. In affected versions, OAuth::Consumer#token_request parses the raw Location header and recursively follows the redirect.

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.

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.

Nodemailer's address parser parses comma-separated addresses in quadratic time (O(n²)) in the number of addresses. A single crafted address string (e.g., To, Cc, Bcc, From, Reply-To) can cause significant slowdown.

Podatność dotyczy niektórych pakietów React Server Components w wersjach 19.x oraz frameworków, które używają tych pakietów, w tym Next.js w wersjach 13.x, 14.x, 15.x i 16.x korzystających z App Router. Problem jest śledzony w systemie jako CVE-2026-23870.

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.

Repeated use of the Unpacker after an error occurs may cause the process to crash with a SEGV. If the Unpacker is used repeatedly to unpack untrusted input from external sources, it may be vulnerable to a DoS attack.

An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service.

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.

In net-ssh, `Service::Forward#initialize` registers server-initiated auth-agent channel handlers unconditionally, so ordinary port forwarding exposes the local SSH agent.

net-ssh's host-certificate verifier (`Net::SSH::HostKeyEntries::CertAuthority#matches_key?`) checks exactly two things when a server presents an OpenSSH certificate (`*[email protected]`) under a `@cert-authority` trusted-CA entry: (1) the cert is self-consistently signed (signature_valid).

Several vulnerabilities have been discovered and fixed in the upstream libvips dependency, two rated as high severity using CVSSv4. Versions of sharp prior to 0.35.0 processing untrusted input are affected.

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.

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.

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.
