UBUNTU-CVE-2014-3509

Race condition in the sslparseserverhellotlsext function in t1lib.c in OpenSSL 1.0.0 before 1.0.0n and 1.0.1 before 1.0.1i, when multithreading and session resumption are used, allows remote SSL servers to cause a denial of service memory overwrite and client application crash or possibly have...

openssl: DoS when sending invalid DTLS handshake

A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash...

Vulnerability in OpenSSL - Crash with SRP ciphersuite in Server Hello message

A crash was found affecting SRP ciphersuites used in a Server Hello message. The issue affects OpenSSL clients and allows a malicious server to crash the client with a null pointer dereference read by specifying an SRP ciphersuite even though it was not properly negotiated with the client. This...

LightsOut/Hello Exploit Kit (CVE-2013-2465)

LightsOut/Hello is an exploit kit that operates by delivering malicious payload to the victim's computer. Remote attackers can infect users by enticing them to visit a malicious web page. Successful infection will allow the attacker to download additional malware to the target...

SOL15343 - OpenSSL vulnerability CVE-2014-0221

The dtls1getmessagefragment function in d1both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service recursion and client crash via a DTLS hello message in an invalid DTLS handshake. CVE-2014-0221...

gnutls: insufficient session id length check in _gnutls_read_server_hello (GNUTLS-SA-2014-3)

A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the...

DEBIAN-CVE-2014-3466

Buffer overflow in the readserverhello function in lib/gnutlshandshake.c in GnuTLS before 3.1.25, 3.2.x before 3.2.15, and 3.3.x before 3.3.4 allows remote servers to cause a denial of service memory corruption or possibly execute arbitrary code via a long session id in a ServerHello message...

GnuTLS Patches Critical Remote Code Execution Bug

GnuTLS, an open source cryptographic library, was a headliner in March because of a critical certificate verification vulnerability that some erroneously put in the same class as Apple’s infamous gotofail bug. The library, used in a number of Linux distributions including Red Hat, Debian and...

USN-2229-1: GnuTLS vulnerability

Joonas Kuorilehto discovered that GnuTLS incorrectly handled Server Hello messages. A malicious remote server or a machine-in-the-middle could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code...
