CVE Vulnerability Catalog

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 8.1.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.

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

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.

libcurl supports pinning of the server certificate public key for HTTPS transfers. Due to an omission, this check is not performed when connecting with QUIC for HTTP/3, when the TLS backend is wolfSSL. Documentation says the option works with wolfSSL, but fails to specify that it does not for QUIC.

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.

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 2.12.10 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.

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 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.

A medium severity vulnerability in CPython where regular expressions allow excessive backtracking during tarfile.TarFile header parsing, leading to ReDoS via specially crafted tar archives.

The urllib.parse.urlsplit() and urlparse() functions in Python improperly validate bracketed hosts (`[]`), accepting hosts that are not IPv6 or IPvFuture. This violates RFC 3986 and could enable SSRF attacks if a URL is processed by multiple URL parsers.

A buffer over-read in PostgreSQL GB18030 encoding validation allows a database input provider to cause temporary denial of service on platforms where a 1-byte over-read leads to process termination. This affects the database server and libpq.

A TOCTOU race condition in pg_dump in PostgreSQL allows an object creator to replace another relation type with a view or foreign table, executing arbitrary SQL functions as the user running pg_dump, often a superuser. The attack requires waiting for the right moment.

When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache entry, making it end sooner or later than otherwise intended. This affects applications using HSTS and URLs with the insecure HTTP:// scheme.

Missing authorization in PostgreSQL built-in views pg_stats_ext and pg_stats_ext_exprs allows an unprivileged database user to read most common values and other statistics from CREATE STATISTICS commands of other users. The most common values may reveal column values the eavesdropper could not otherwise see.
