CVE-2012-1165

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...

CVE-2012-0884

CVE-2012-0884 affects the OpenSSL CMS/PKCS#7 implementations. The vulnerability arises from an improper restriction of oracle behavior, enabling context-dependent attackers to decrypt data via a Million Message Attack (MMA) under certain conditions. The issue is present in OpenSSL versions prior ...

UBUNTU-CVE-2012-0884

The implementation of Cryptographic Message Syntax CMS and PKCS 7 in OpenSSL before 0.9.8u and 1.x before 1.0.0h does not properly restrict certain oracle behavior, which makes it easier for context-dependent attackers to decrypt data via a Million Message Attack MMA adaptive chosen ciphertext...

CVE-2011-4354

crypto/bn/bnnist.c in OpenSSL before 0.9.8h on 32-bit platforms, as used in stunnel and other products, in certain circumstances involving ECDH or ECDHE cipher suites, uses an incorrect modular reduction algorithm in its implementation of the P-256 and P-384 NIST elliptic curves, which allows...

CVE-2011-4354

crypto/bn/bnnist.c in OpenSSL before 0.9.8h on 32-bit platforms, as used in stunnel and other products, in certain circumstances involving ECDH or ECDHE cipher suites, uses an incorrect modular reduction algorithm in its implementation of the P-256 and P-384 NIST elliptic curves, which allows...

openssl: malformed RFC 3779 data can cause assertion failures

OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC 3779 support is enabled, allows remote attackers to cause a denial of service assertion failure via an X.509 certificate containing certificate-extension data associated with 1 IP address blocks or 2 Autonomous System AS identifiers...

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...

CVE-2012-0050

OpenSSL 0.9.8s and 1.0.0f does not properly support DTLS applications, which allows remote attackers to cause a denial of service crash via unspecified vectors related to an out-of-bounds read. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-4108...

CVE-2011-4619

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...

CVE-2011-4109

OpenSSL 0.9.7 < 0.9.7f Vulnerability

The version of OpenSSL installed on the remote host is prior to 0.9.7f. It is, therefore, affected by a vulnerability as referenced in the 0.9.7f advisory. - The derchop script in the openssl package in Trustix Secure Linux 1.5 through 2.1 and other operating systems allows local users to overwri...

OpenSSL 0.9.8 < 0.9.8j Vulnerability

The version of OpenSSL installed on the remote host is prior to 0.9.8j. It is, therefore, affected by a vulnerability as referenced in the 0.9.8j advisory. - OpenSSL 0.9.8i and earlier does not properly check the return value from the EVPVerifyFinal function, which allows remote attackers to bypa...
