CVE Vulnerability Catalog

In the Linux kernel, a vulnerability was found in the F2FS filesystem involving uninitialized value access in the f2fs_sanity_check_node_footer function. The issue was reported by syzbot and may lead to unpredictable system behavior.

A vulnerability in SEV (Secure Encrypted Virtualization) firmware causes insufficient or incomplete data removal in a hardware component, resulting in incomplete IOMMU flushing. This can potentially lead to a loss of confidentiality and integrity in guest memory.

An issue was discovered in py-lmdb 0.97 where mdb_page_touch does not properly set up mc->mc_pg[mc->top] for certain mp_flags values, leading to an invalid write operation. The vulnerability can be triggered by supplying a crafted data.mdb file.

A vulnerability in CPython (from version 0 to 3.6.13, 3.7.0-3.7.10, 3.8.0-3.8.8, 3.9.0-3.9.2) allows Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs functions. An attacker can use a technique called 'parameter cloaking' to manipulate query parameters.

An improper access control vulnerability in AMD Secure Encrypted Virtualization (SEV) firmware allows a malicious hypervisor to bypass RMP protections, potentially compromising SEV-SNP guest memory integrity.

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok() on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directories.

The 'id' utility in uutils coreutils incorrectly displays data in 'pretty print' mode when the real UID differs from the effective UID. The implementation mistakenly uses the effective GID instead of the effective UID when looking up the name of the effective user, leading to misleading output.

A vulnerability in the tail utility of uutils coreutils allows exfiltration of sensitive file contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting its contents.

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 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 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.

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 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.

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 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.

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.
