openssl: DoS due to improper handling of OCSP response verification

OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d does not properly perform signature verification for OCSP responses, which allows remote OCSP servers to cause a denial of service NULL pointer dereference and application crash via an invalid key...

Ubuntu 12.04 LTS / 12.10 : openssl vulnerability (USN-1732-3)

USN-1732-1 fixed vulnerabilities in OpenSSL. The fix for CVE-2013-0169 and CVE-2012-2686 was reverted in USN-1732-2 because of a regression. This update restores the security fix, and includes an extra fix from upstream to address the AES-NI regression. We apologize for the inconvenience. Adam...

Ubuntu 7.04 / 7.10 / 8.04 LTS : openssl vulnerability (USN-612-1)

A weakness has been discovered in the random number generator used by OpenSSL on Debian and Ubuntu systems. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledg...

openssl: mime_param_cmp NULL dereference crash

The mimeparamcmp function in crypto/asn1/asnmime.c in OpenSSL before 0.9.8u and 1.x before 1.0.0h allows remote attackers to cause a denial of service NULL pointer dereference and application crash via a crafted S/MIME message, a different vulnerability than CVE-2006-7250...

openssl: SGC restart DoS attack

The Server Gated Cryptography SGC implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service CPU consumption via unspecified vectors...

DEBIAN-CVE-2011-5095

The Diffie-Hellman key-exchange implementation in OpenSSL 0.9.8, when FIPS mode is enabled, does not properly validate a public parameter, which makes it easier for man-in-the-middle attackers to obtain the shared secret key by modifying network traffic, a related issue to CVE-2011-1923...

Name of the Vulnerable Software and Affected Versions OpenSSL versions prior to 0.9.8l OpenSSL versions 0.9.8m through 1.x Description The issue allows remote attackers to cause a denial of service, specifically CPU consumption, by performing many renegotiations within a single connection. This i...

OpenSSL 1.0.0 < 1.0.0j Vulnerability

The version of OpenSSL installed on the remote host is prior to 1.0.0j. It is, therefore, affected by a vulnerability as referenced in the 1.0.0j advisory. - Integer underflow in OpenSSL before 0.9.8x, 1.0.0 before 1.0.0j, and 1.0.1 before 1.0.1c, when TLS 1.1, TLS 1.2, or DTLS is used with CBC...

OpenSSL 0.9.8 < 0.9.8x Vulnerability

openssl: asn1_d2i_read_bio integer errors leading to buffer overflow

The asn1d2ireadbio function in crypto/asn1/ad2ifp.c in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1 before 1.0.1a does not properly interpret integer data, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service memory corruption or possibly have...

CVE-2012-2131

Multiple integer signedness errors in crypto/buffer/buffer.c in OpenSSL 0.9.8v allow remote attackers to conduct buffer overflow attacks, and cause a denial of service memory corruption or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an...
