CVE Vulnerability Catalog

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 was found in the brace-expansion library up to versions 1.1.11, 2.0.1, 3.0.0, and 4.0.0, involving inefficient regular expression complexity in the expand function in index.js. The attack can be launched remotely.

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 vulnerability in python-cryptography 3.2 allows Bleichenbacher timing attacks on the RSA decryption API. Attackers can exploit timing differences in processing valid PKCS#1 v1.5 ciphertext.

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 systemd causes systemd-coredump to ignore the kernel's fs.suid_dumpable setting, potentially leading to a local information leak.

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.

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.

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.

The golang.org/x/crypto/openpgp package is unsafe by design, has numerous known security issues, is not maintained, and should not be used. It is recommended to use the maintained package github.com/ProtonMail/go-crypto/openpgp instead.

A flaw in shadow-utils fails to properly clear the buffer when a new password is entered twice and the second attempt fails. This leaves the first password in memory, potentially allowing an attacker with sufficient access to retrieve it.

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.

Vulnerability in CPAN 2.28 allows signature verification bypass. An attacker can supply unauthorized code that is treated as properly signed.

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 OpenSSL library allows unbounded memory growth when processing TLSv1.3 sessions in certain non-default server configurations. An attacker can exploit this to cause a Denial of Service (DoS).

A vulnerability was found in systemd where a service using the DynamicUser property can create a SUID/SGID binary that remains executable with the transient service UID/GID even after the service terminates. A local attacker could exploit this to access resources owned by a potentially different UID/GID.

Processing a maliciously formatted PKCS12 file may cause OpenSSL to crash, leading to a potential Denial of Service attack. Applications loading PKCS12 files from untrusted sources might terminate abruptly.
