Improper Validation of Specified Quantity in Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input due to improper handling of oversized Subject Alternative Name fields during certificate validation. An attacker can bypass certificate validation by crafting a certificate with an...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation due to improper handling of Uniform Resource Identifier URI and Service SRV Subject Alternative Names SANs in the certificate validation process. An attacker can intercept sensitive information or...

[SECURITY] Fedora 44 Update: tinyproxy-1.11.2-7.fc44

tinyproxy is a small, efficient HTTP/SSL proxy daemon that is very useful in a small network setting, where a larger proxy like Squid would either be too resource intensive, or a security risk...

gnutls: GnuTLS: Denial of Service via excessive resource consumption during certificate verification

A flaw was found in GnuTLS. This vulnerability allows a denial of service DoS by excessive CPU Central Processing Unit and memory consumption via specially crafted malicious certificates containing a large number of name constraints and subject alternative names SANs...

GHSA-XX5W-CVP6-JV83 Wasmtime with Winch compiler backend on aarch64 may allow a sandbox-escaping memory access

Impact Wasmtime with its Winch baseline non-default compiler backend may allow properly constructed guest Wasm to access host memory outside of its linear-memory sandbox. This vulnerability requires use of the Winch compiler -Ccompiler=winch. By default, Wasmtime uses its Cranelift backend, not...

golang: crypto/x509: excluded subdomain constraint does not restrict wildcard SANs

A flaw was found in the crypto/x509 package in the Go standard library. This vulnerability allows a certificate validation bypass via an excluded subdomain constraint in a certificated chain as it does not restrict the usage of wildcard SANs in the leaf certificate...

EUVD-2026-21290

An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect...

Integer Underflow (Wrap or Wraparound)

Overview Affected versions of this package are vulnerable to Integer Underflow Wrap or Wraparound in the parsing of the Subject Alternative Name extension of X.509 certificates due to improper handling of entry lengths in the process. An attacker can cause incorrect processing of certificate data...
