Debian DSA-2390-1 : openssl - several vulnerabilities

Several vulnerabilities were discovered in OpenSSL, an implementation of TLS and related protocols. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities : - CVE-2011-4108 The DTLS implementation performs a MAC check only if certain padding is valid, which make...

FreeBSD : OpenSSL -- multiple vulnerabilities (78cc8a46-3e56-11e1-89b4-001ec9578670)

The OpenSSL Team reports : 6 security flaws have been fixed in OpenSSL 1.0.0f : If X509VFLAGPOLICYCHECK is set in OpenSSL 0.9.8, then a policy check failure can lead to a double-free. OpenSSL prior to 1.0.0f and 0.9.8s failed to clear the bytes used as block cipher padding in SSL 3.0 records. As ...

CVE-2011-4576

The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer...

CVE-2011-4576

OpenSSL CVE-2011-4576 affects SSL 3.0 padding initialization: the implementation does not properly initialize data structures for block cipher padding, allowing a remote attacker to potentially recover plaintext by decrypting the padding data. Affected releases: OpenSSL before 0.9.8s and 1.x befo...

CVE-2011-4108

The CVE-2011-4108 issue concerns the DTLS implementation in OpenSSL. Affected versions are OpenSSL before 0.9.8s and OpenSSL 1.x before 1.0.0f, where a MAC check is performed only if certain padding is valid, enabling a padding oracle that can aid plaintext recovery. This is explicitly described ...
