CVE Vulnerability Catalog

In libxml2 before 2.13.8 and 2.14.2, a heap-based buffer under-read exists in xmlSchemaIDCFillNodeTables in xmlschemas.c. Exploitation requires validation of a crafted XML document against an XML schema with identity constraints or a crafted schema.

In the cryptography package for Python before version 3.3.2, sequences of update calls for symmetric encryption of multi-GB data can cause integer overflow and buffer overflow, as demonstrated with the Fernet class.

The Go HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. The fix prevents sending requests with invalid Request.Host or Request.URL.Host values.

The issue was addressed with improved memory handling. It is fixed in macOS Ventura 13.6, tvOS 17, iOS 16.7 and iPadOS 16.7, macOS Monterey 12.7, watchOS 10, iOS 17 and iPadOS 17, macOS Sonoma 14. Processing web content may disclose sensitive information.

A vulnerability in the Go crypto/tls library allows a DoS attack by sending extremely large RSA keys in certificate chains, causing high CPU usage during signature verification. The fix restricts RSA key sizes transmitted during handshakes to a maximum of 8192 bits.

In libxslt before 1.1.43, xsltGetInheritedNsList has a use-after-free issue related to exclusion of result prefixes.

A flaw in GnuPG before version 2.2.18 allows certificate signature forgery using SHA-1 collision attacks. An attacker can create forged certificate signatures, compromising authentication integrity.

A race condition in the Go database/sql package can overwrite expected results when a query is cancelled during the Scan method call while other queries run in parallel.

GNU Midnight Commander 4.8.29-146-g299d9a2fb was found to contain a NULL pointer dereference in the function x_error_handler() at tty/x11conn.c. NOTE: this is disputed because it should be categorized as a usability problem (an X operation silently fails).

Multiple security vulnerabilities have been identified in the grpc-go library affecting the xDS RBAC authorization engine and the HTTP/2 transport server implementation. These vulnerabilities could lead to authorization bypass (Fail-Open) during rule translation.

The RedirectSlashes function in middleware/strip.go is vulnerable to host header injection leading to an open redirect. This is considered lower-severity as it cannot be exploited from browsers or email clients.

A vulnerability was found in PHP where setting the environment variable PHP_CLI_SERVER_WORKERS to a large value leads to a heap buffer overflow.

Checking excessively long DSA keys or parameters may be very slow. Applications using EVP_PKEY_param_check() or EVP_PKEY_public_check() to verify DSA public keys or parameters may experience long delays.

A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames, it calls free() on an uninitialized pointer, leading to a segmentation fault and potential denial of service.

A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the application compiled against openjpeg.

An integer overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of Service (DoS). This occurs when using the "-ImgDir" command line option on a directory containing 1048576 files.

The Diffie-Hellman Key Agreement Protocol allows long exponents, making certain calculations unnecessarily expensive. The 1996 van Oorschot and Wiener paper showed that appropriately short exponents can be used with adequate subgroup constraints, but these are not utilized.

A vulnerability in cross-origin redirect handling causes Proxy-Authorization and Proxy-Authenticate headers to persist, potentially leaking sensitive authentication data.

In CPython's 'http.cookies' module, parsing cookies with backslash-escaped characters uses a quadratic algorithm, causing excessive CPU usage.

In Vim before 9.1.0764, a use-after-free occurs when closing a buffer and a BufWinLeave auto command reopens the same buffer in a new split window.
