CVE Vulnerability Catalog

A high severity vulnerability in the CPython zipfile module affecting zipfile.Path. When iterating over entry names in a zip archive (e.g., namelist(), iterdir()), unexpected behavior may occur. The more common zipfile.ZipFile class is unaffected.

NSSCryptoSignBackend.cc in Poppler before 25.04.0 does not verify adbe.pkcs7.sha1 signatures on documents, allowing potential signature forgeries.

Poppler before 25.04.0 allows crafted input files to trigger out-of-bounds reads in the JBIG2Bitmap::combine function in JBIG2Stream.cc due to a misplaced isOk check.

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.

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.

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.

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

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 2.12.10 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 2.13.8 and 2.14.2, out-of-bounds memory access occurs in the Python API due to an incorrect return value in xmlPythonFileRead and xmlPythonFileReadRaw.

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 divide-by-zero error was discovered in py-lmdb 0.97 in the mdb_env_open2 function when mdb_env_read_header obtains a zero value for a certain size field. This issue can be triggered by supplying a crafted data.mdb file.

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.

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

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.

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 PHP versions 8.1.x before 8.1.31, 8.2.x before 8.2.26, 8.3.x before 8.3.14, the convert.quoted-printable-decode filter can cause a buffer overread by one byte, potentially leading to crashes or disclosure of other memory areas.

In PHP versions 8.1.x before 8.1.31, 8.2.x before 8.2.26, 8.3.x before 8.3.14, when using streams with a configured proxy and the request_fulluri option, the URI is not properly sanitized, which can lead to HTTP request smuggling and allow the attacker to perform arbitrary HTTP requests through the proxy.

In PHP versions 8.3.x before 8.3.19 and 8.4.x before 8.4.5, a code sequence involving the __set handler or ??= operator and exceptions can lead to a use-after-free vulnerability.

In PHP versions 8.1.x before 8.1.31, 8.2.x before 8.2.26, 8.3.x before 8.3.14, uncontrolled long string inputs to the ldap_escape() function on 32-bit systems can cause an integer overflow, resulting in an out-of-bounds write.
