CVE Vulnerability Catalog

The development server contains a path traversal vulnerability on Windows when serving files from `servedir`. Due to the use of `path.Clean()` (which only normalizes forward-slash `/` separators) instead of a Windows-aware path normalization function, it is possible to craft malicious requests.

In the cryptography package for Python before version 3.3.2, sequences of update calls for symmetric encryption of multi-GB data can cause integer overflow and buffer overflow, as demonstrated with the Fernet class.

A vulnerability in Go's HTTP/2 implementation allows a malicious client to rapidly create and reset requests, causing excessive server resource consumption. Although the number of concurrent streams is limited by MaxConcurrentStreams, resetting requests enables the attacker to continuously send new requests.

The filepath package in Go does not recognize paths with a \??\ prefix as special. On Windows, a path starting with \??\ is equivalent to a path starting with \\?\ and can be used to access arbitrary system locations.

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.

The Go HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. The fix prevents sending requests with invalid Request.Host or Request.URL.Host values.

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.

CPAN.pm before version 2.35 does not verify TLS certificates when downloading distributions over HTTPS. This allows man-in-the-middle attackers to replace downloaded packages with malicious ones.

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 vulnerability in the Go crypto/tls library allows a DoS attack by sending extremely large RSA keys in certificate chains, causing high CPU usage during signature verification. The fix restricts RSA key sizes transmitted during handshakes to a maximum of 8192 bits.

A vulnerability in the Go net/http library allows a malicious HTTP sender to use chunk extensions to force a receiver to read many more bytes from the network than are in the body. A malicious HTTP client can exploit this to cause a server to automatically read a large amount of data (up to about 1 GiB).

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 pip package before version 19.2 for Python is vulnerable to directory traversal when a URL is provided in an install command. An attacker can exploit a Content-Disposition header containing '../' in the filename to overwrite files, such as /root/.ssh/authorized_keys.

In the Linux kernel, a vulnerability in KVM for AMD SEV-SNP was found. During SNP launch finish, the synchronization and encryption of VMSA (Virtual Machine Save Area) does not lock all vCPUs, allowing userspace to manipulate or run a vCPU while its state is being synchronized.

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.

In the Linux kernel, a vulnerability was found in the mechanism preventing timer interrupt starvation. Missing resets of the next_event_forced flag in several places, such as when the clock event state changes, may cause incorrect behavior.
