CVE Vulnerability Catalog

Loofah::HTML5::Scrub.allowed_uri? does not correctly reject javascript: or vbscript: URIs when the scheme is split by a numeric character reference that has no trailing semicolon. A browser decodes such references and resolves the URL to an executable javascript: scheme, while allowed_uri? considers it safe.

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 2.13.8 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.

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.

HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack.

HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.

Faulty input validation in the core of Apache HTTP Server through 2.4.58 allows malicious or exploitable backend/content generators to split HTTP responses, leading to HTTP response splitting attacks.

Vim is an improved version of the Unix vi text editor. When flushing the typeahead buffer, Vim moves the current position in the typeahead buffer but does not check whether there is enough space left in the buffer to handle the next characters. This may lead to the tb_off position within the buffer being out of bounds.

Setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. A path traversal vulnerability in PackageIndex is present in setuptools prior to version 78.1.1. An attacker can write files to arbitrary locations on the filesystem.

Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows request URLs with incorrect encoding to be sent to backend services, potentially bypassing authentication via crafted requests.

Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerable to information disclosure, SSRF or local script execution via backend applications whose response headers are malicious or exploitable.

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.

Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe RewriteRules to unexpectedly setup URLs to be handled by mod_proxy.

There is a possible cross-site scripting vulnerability in rails-html-sanitizer when the sanitizer is configured to allow an SVG reference element such as <use>. This is related to GHSA-9wjq-cp2p-hrgf in Loofah, whose SVG local-reference logic rails-html-sanitizer mirrors.

In PHP from 8.1.* before 8.1.32, 8.2.* before 8.2.28, 8.3.* before 8.3.19, 8.4.* before 8.4.5, when user-supplied headers are sent, insufficient validation of end-of-line characters may prevent certain headers from being sent or lead to certain headers being misinterpreted.
