CVE Vulnerability Catalog

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.

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.

In NTFS-3G through version 2026.2.25, a heap buffer overflow exists in the ntfs_ir_to_ib() function in index.c. An attacker can exploit this by crafting a malicious NTFS image that, when mounted and a directory is extended (e.g., by creating a file), corrupts heap memory in the SUID-root ntfs-3g binary.

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.

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.

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.

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.

Insufficient checks of the RMP on host buffer access in IOMMU may allow an attacker with privileges and a compromised hypervisor to trigger an out of bounds condition without RMP checks, resulting in a potential loss of confidential guest integrity.

In NTFS-3G through version 2026.2.25, a heap buffer overflow exists in the cat() function in cat.c. An attacker can exploit this by crafting a malicious NTFS image that, when a file is read, corrupts heap memory in the ntfscat binary.

Nokogiri's CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an XML attribute. If Ruby code had already accessed an attribute child node, `Nokogiri::XML::Attr#value=` could free the underlying native child node while the wrapper remains.

The vulnerability in the Nokogiri library causes `Nokogiri::XML::XPathContext` to not keep its source document alive for garbage collection. If an XPathContext outlives its document and the document is collected, evaluating an XPath expression could read invalid memory and potentially segfault.

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=.

Nokogiri has a bug in methods called on allocated-but-uninitialized native wrapper classes inheriting from `Nokogiri::XML::Node`. This causes a NULL pointer dereference that could crash the process.

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.

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.

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.

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.

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.

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.
