CVE Vulnerability Catalog

The net-tools package up to version 2.10 does not properly validate the structure of /proc files, which may lead to errors when reading data.

In libxslt before 1.1.43, numbers.c has a use-after-free because in nested XPath evaluations, an XPath context node can be modified but never restored. Affects xsltNumberFormatGetValue, xsltEvalXPathPredicate, xsltEvalXPathStringNs, and xsltComputeSortResultInternal.

In CPython, the email module does not properly quote newlines in email headers during serialization, allowing header injection when an email is serialized. This is a medium severity vulnerability.

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

Sudo VISudo version 1.6.8 and earlier allows local users to corrupt arbitrary files via a symlink attack on temporary files.

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 timing side-channel in ECDSA signature computations could potentially allow recovering the private key by an attacker. Measuring timing could lead to private key recovery.

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.

A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption.

In libxml2 before 2.12.10 and 2.13.6, a NULL pointer dereference exists in xmlPatMatch in pattern.c.

In libxml2 before 2.13.8 and 2.14.2, out-of-bounds memory access occurs in the Python API due to an incorrect return value in xmlPythonFileRead and xmlPythonFileReadRaw.

A flaw was found in GnuTLS related to the Minerva attack, a cryptographic vulnerability that exploits deterministic behavior, leading to side-channel leaks. In specific scenarios, such as using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce values.

Use of the low-level GF(2^m) elliptic curve APIs with untrusted explicit values for the field polynomial can lead to out-of-bounds memory reads or writes.

In libxml2 before 2.12.10 and 2.13.6, a stack-based buffer overflow exists in xmlSnprintfElements in valid.c. Exploitation requires DTD validation of an untrusted document or untrusted DTD. Similar to CVE-2017-9047.

In libxml2 before 2.12.10 and 2.13.6, a use-after-free exists in xmlSchemaIDCFillNodeTables and xmlSchemaBubbleIDCNodeTables in xmlschemas.c. Exploitation requires validation of a crafted XML document against an XML schema with identity constraints or a crafted schema.

In libxml2 before 2.11.0, xmlXIncludeAddNode in xinclude.c has a use-after-free vulnerability.

A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This may allow an attacker to trigger memory allocation failures, causing a segmentation fault and application crash.

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.

In sshd in OpenSSH before version 10.0, the DisableForwarding directive does not adhere to documentation, failing to disable X11 and agent forwarding.

In CPython, the venv module and CLI do not properly quote paths when creating a virtual environment, allowing injection of commands into activation scripts (e.g., source venv/bin/activate). This enables arbitrary code execution upon activation.
