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.

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.

GNU libidn2 before version 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels, allowing domain impersonation in some circumstances. An attacker can create a malicious domain that matches a target domain except for certain characters.

An out-of-bounds read/write vulnerability was found in e2fsprogs 1.46.5. This issue leads to a segmentation fault and possibly arbitrary code execution via a specially crafted filesystem.

SQLite 3.30.1 mishandles certain SELECT statements with a nonexistent VIEW, leading to an application crash.

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

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.

In GCC 4.1 through 8, the stack_protect_prologue and stack_protect_epilogue functions for ARM targets generate instruction sequences that spill the address of the stack protector guard. This allows an attacker to bypass the stack protector mechanism.

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.

Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served but not directly reachable, leading to code execution or source code disclosure.

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.

SSH clients that receive SSH_AGENT_SUCCESS when expecting a typed response will panic and cause early termination of the client process.

Vulnerability in Libgcrypt before versions 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption due to missing exponent blinding, enabling a side-channel attack on mpi_powm. Additionally, the window size is not chosen appropriately, increasing information leakage risk.

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.

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.

It was discovered that a systemd service using the DynamicUser property can gain new privileges through the execution of SUID binaries, allowing creation of binaries owned by the service's transient group with the setgid bit set. A local attacker may exploit this flaw to access resources that will be.

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.

A flaw was found in Python's urllib.parse module where the urlparse method does not sanitize input, allowing characters like ' ' and ' ' in the URL path. This can lead to CRLF injection attacks.

An out-of-bounds write vulnerability was found in glibc before version 2.31 when handling signal trampolines on PowerPC. The backtrace function did not properly check array bounds when storing the frame address, leading to denial of service or potential code execution.

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.
