CVE Vulnerability Catalog

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.

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.

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).

The IsLocal function on Windows incorrectly detects reserved device names in some cases. Reserved names followed by spaces (e.g., "COM1 ") and names "COM" and "LPT" with superscript 1, 2, or 3 are incorrectly reported as local. The fix ensures IsLocal now correctly identifies these.

A vulnerability in the Go standard library (net/http) causes the HTTP client to not forward sensitive headers like Authorization or Cookie when following a redirect to a domain that is not a subdomain or exact match of the original domain. For example, a redirect from foo.com to www.foo.com will forward the Authorization header, but a redirect to a different domain will not.

A vulnerability in Go's html/template package allows bypassing contextual auto-escaping if errors returned by MarshalJSON methods contain user-controlled data. This can lead to injection of unexpected content into HTML templates.

A vulnerability in the Go standard parser causes a panic when processing source code with deeply nested literals. The issue stems from stack exhaustion during recursive parsing.

A vulnerability in the archive/zip package of Go causes its handling of certain invalid zip files to differ from most zip implementations. This discrepancy can be exploited to create a zip file whose content varies depending on the reading implementation. The archive/zip package now rejects such files.

The Go HTTP client drops sensitive headers (e.g., Authorization) after a cross-domain redirect, but may re-send them on a subsequent same-domain redirect, posing a potential data leak risk.

A vulnerability in the os package of the Go standard library allows improper access to the parent directory of an os.Root by opening a filename ending in "../". For example, Root.Open("../") opens the parent directory, bypassing access restrictions.

A vulnerability in the assembly implementation of an internal cryptographic function on the ppc64le architecture leaks a few bits of secret scalars due to the use of a variable-time instruction. Based on how this function is used, the leakage is not sufficient to recover the private key.

The RedirectSlashes function in middleware/strip.go is vulnerable to host header injection leading to an open redirect. This is considered lower-severity as it cannot be exploited from browsers or email clients.

A race condition in the Go database/sql package can overwrite expected results when a query is cancelled during the Scan method call while other queries run in parallel.

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.

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.

Crass recursively parses CSS simple blocks and functions without a depth guard, allowing an attacker to cause stack overflow or excessive memory usage via deeply nested blocks.

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.

A vulnerability in libfuse versions 3.18.0 through 3.18.1 causes a NULL pointer dereference and memory leak in the fuse_uring_init_queue function. A local user can exploit this to crash the FUSE daemon or exhaust system resources.

A vulnerability in the Crass library involves unbounded exponentiation when converting CSS scientific notation number values before clamping the result to Float::MAX. Applications that use Crass to parse attacker-controlled CSS strings can be forced to consume excessive CPU and memory when processing a tiny input.
