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.

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.

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.

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.

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

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.

The email module in Python through 3.11.3 incorrectly parses email addresses containing special characters. The wrong portion of an RFC2822 header is identified as the value of the addr-spec.

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.

Serving WebSocket protocol upgrades over an HTTP/2 connection could result in a Null Pointer dereference, leading to a crash of the server process, degrading performance.

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 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 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.

Vulnerability in CPAN 2.28 allows signature verification bypass. An attacker can supply unauthorized code that is treated as properly signed.

A flaw in shadow-utils fails to properly clear the buffer when a new password is entered twice and the second attempt fails. This leaves the first password in memory, potentially allowing an attacker with sufficient access to retrieve it.

The pip package before version 19.2 for Python is vulnerable to directory traversal when a URL is provided in an install command. An attacker can exploit a Content-Disposition header containing '../' in the filename to overwrite files, such as /root/.ssh/authorized_keys.

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).

CPAN.pm before version 2.35 does not verify TLS certificates when downloading distributions over HTTPS. This allows man-in-the-middle attackers to replace downloaded packages with malicious ones.

Windows libarchive has a remote code execution vulnerability. Technical details are not provided in the description.

A vulnerability in systemd causes systemd-coredump to ignore the kernel's fs.suid_dumpable setting, potentially leading to a local information leak.
