SOL93600123 - OpenSSL vulnerability CVE-2016-2107

2 IPsec is vulnerable only in phase 1 IKE racoon, if configured to use AES-CBC. Vulnerability Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Versions known to be no...

CVE-2016-2107

CVE-2016-2107 (OpenSSL) is a padding-oracle vulnerability in the AES-NI CBC MAC check. The issue arises in the AES-CBC padding validation where memory allocation during the padding check is mishandled, enabling potential leakage of plaintext under certain conditions. Affected OpenSSL versions inc...

Debian DSA-3566-1 : openssl - security update

Several vulnerabilities were discovered in OpenSSL, a Secure Socket Layer toolkit. - CVE-2016-2105 Guido Vranken discovered that an overflow can occur in the function EVPEncodeUpdate, used for Base64 encoding, if an attacker can supply a large amount of data. This could lead to a heap corruption....

Amazon Linux AMI : openssl (ALAS-2016-695)

A vulnerability was discovered that allows a man-in-the-middle attacker to use a padding oracle attack to decrypt traffic on a connection using an AES CBC cipher with a server supporting AES-NI. CVE-2016-2107 , Important It was discovered that the ASN.1 parser can misinterpret a large universal t...

openssl: multiple issues

CVE-2016-2105 buffer overflow: An overflow can occur in the EVPEncodeUpdate function which is used for Base64 encoding of binary data. If an attacker is able to supply very large amounts of input data then a length check can overflow resulting in a heap corruption. Internally to OpenSSL the...

Debian DLA-456-1 : openssl security update

Several vulnerabilities were discovered in OpenSSL, a Secure Socket Layer toolkit. CVE-2016-2105 Guido Vranken discovered that an overflow can occur in the function EVPEncodeUpdate, used for Base64 encoding, if an attacker can supply a large amount of data. This could lead to a heap corruption...
