CVE Vulnerability Catalog

A critical vulnerability was found in SQLite3 up to version 3.43.0 in the sessionReadRecord function of ext/session/sqlite3session.c. Manipulation leads to a heap-based buffer overflow, potentially allowing remote code execution.

A vulnerability in SQLite up to version 3.30.1 allows attackers to trigger infinite recursion via certain types of self-referential views in conjunction with ALTER TABLE statements.

No description is available for CVE-2026-6502. The nature of the vulnerability cannot be determined.

The vulnerability in the Crass library causes unbounded processing of scientific notation in CSS values before clamping the result to Float::MAX. An attacker can send a small crafted CSS string that forces excessive CPU and memory consumption.

A vulnerability in the Crass library causes excessive CPU consumption when parsing input containing non-ASCII characters. Inefficient tracking of multi-byte character positions leads to superlinear parsing time.

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

The CIL compiler in SELinux 3.2 has a use-after-free vulnerability in the __cil_verify_classperms function, called from __cil_verify_classpermission and __cil_pre_verify_helper.

The html.Parse function in golang.org/x/net/html has quadratic parsing complexity for specially crafted HTML inputs, which can lead to denial of service (DoS).

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 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.

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.

The libpcre library in PCRE before version 8.44 is vulnerable to an integer overflow. The issue occurs when a large number is used after the (?C substring in a regular expression.

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.

A timing attack vulnerability on the ECDSA algorithm was discovered in the libgcrypt20 cryptographic library. An attacker can exploit timing differences in cryptographic operations to recover the private key.

A vulnerability in the Crass library allows a DoS attack by providing a stylesheet with a very large number of adjacent CSS comments when the :preserve_comments option is disabled (default behavior). This causes excessive recursion and potential system resource exhaustion.

A flaw in glibc may cause the gaih_inet function to use freed memory in uncommon situations, leading to an application crash. This issue is only exploitable when getaddrinfo is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=.

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.

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.

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 the libcurl library causes a memory leak when handling HTTP/2 server push. When an application allows server push and the number of headers exceeds the limit of 1000, libcurl aborts the push but fails to free previously allocated headers.
