RHEL 7 : gnutls (RHSA-2026:43575)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:43575 advisory. The gnutls packages provide the GNU Transport Layer Security GnuTLS library, which implements cryptographic algorithms and protocols such a...

CVE-2026-16318 QUIC Transport Parameters Memory Leak During HelloRetryRequest in s2n-tls

The QUIC transport parameters extension handler in s2n-tls incorrectly uses s2nalloc instead of s2nrealloc to store the peer's transport parameters. When a TLS 1.3 connection goes through a HelloRetryRequest, the handler is called twice on the same connection. On the second call, s2nalloc zeroes...

The vulnerability of the parse_handshake_header() function in the GnuTLS cryptographic library allows a attacker to induce a service failure.

The vulnerability of the parsehandshakeheader function in the GnuTLS cryptographic library is related to integer overflow. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

curl: Trailing-dot IPv4 URL bypasses IP-address guard, allows wildcard DNS SAN match

Hi all, Sorry to ruin anybody's day, but we've discovered another issue when it comes to dots. We've found a TLS certificate verification bypass that lets a trailing-dot IPv4 URL -- https://127.0.0.1./ -- pass peer authentication against a wildcard DNS SAN certificate such as DNS:.0.0.1. The IP...

The vulnerability of the Cisco IOS XE operating system’s TLS library allows attackers to trigger memory exhaustion or service failure.

The vulnerability of the Cisco IOS XE operating system’s TLS library is related to the absence of references to an active, allocated resource. Exploiting this vulnerability can allow a malicious actor to induce memory exhaustion or service failure from a remote perspective...
