CVE Vulnerability Catalog

A vulnerability in the DNS protocol, related to the Closest Encloser Proof aspect in RFC 5155 (when RFC 9276 guidance is skipped), allows remote attackers to cause a denial of service (DoS) by triggering excessive CPU consumption for SHA-1 computations. The attack involves sending DNSSEC responses in a random subdomain attack, known as the NSEC3 issue.

In the POWER9 backend of GCC before version 10, optimization of multiple calls to the __builtin_darn intrinsic into a single call reduces the entropy of the random number generator. This occurs because a volatile operation was not specified.

A vulnerability in Perl 5.30.0 through 5.38.0 allows a heap buffer overflow when compiling a crafted regular expression. An attacker can exploit this to cause a controlled buffer overflow.

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 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.

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.

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 denial-of-service vulnerability exists in Engine.IO / Socket.IO servers that allow transport upgrades. The Engine.IO protocol revision is negotiated during the initial handshake and stored on the session, but a newly-created transport, including a WebSocket upgrade transport, could be exploited to overload the server.
