Debian DLA-1701-1 : openssl security update

Juraj Somorovsky, Robert Merget and Nimrod Aviram discovered a padding oracle attack in OpenSSL. If an application encounters a fatal protocol error and then calls SSLshutdown twice once to send a closenotify, and once to receive one then OpenSSL can respond differently to the calling application...

Padding Oracle Attack

openssl is vulnerable to padding oracle attacks. In the event of a fatal protocol error and SSLshutdown is called twice, an attacker is able to perform a padding oracle attack to decrypt data by sending a 0 byte record with invalid padding, causing the application to behave differently due to...

Padding Oracle Attack

httpd is vulnerable to padding oracle attack. It was discovered that the modsessioncrypto module of httpd did not use any mechanisms to verify integrity of the encrypted session data stored in the user's browser. A remote attacker could use this flaw to decrypt and modify session data using a...

Moderate severity vulnerability that affects org.bouncycastle:bcprov-jdk14 and org.bouncycastle:bcprov-jdk15

In the Bouncy Castle JCE Provider version 1.55 and earlier the DHIES/ECIES CBC mode vulnerable to padding oracle attack. For BC 1.55 and older, in an environment where timings can be easily observed, it is possible with enough observations to identify when the decryption is failing due to padding...

FreeBSD : tinc -- Buffer overflow (a4eb38ea-cc06-11e8-ada4-408d5cf35399)

tinc-vpn.org reports : The authentication protocol allows an oracle attack that could potentially be exploited. If a man-in-the-middle has intercepted the TCP connection it might be able to force plaintext UDP packets between two nodes for up to a PingInterval period. C Tenable Network Security,...
