CVE-2013-1619

The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28, and 3.1.x before 3.1.7 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks...

CVE-2013-1623

The TLS and DTLS implementations in wolfSSL CyaSSL before 2.5.0 do not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks...

Cross-VM Side-channel attacks against cryptography keys

A group of researchers has developed a side-channel attack targeting virtual machines that could pose a threat to cloud computing environments. Side-channel attacks against cryptography keys have, until now, been limited to physical machines, this attack is the first such attack demonstrated on a...

Side-Channel Attack Steals Crypto Key from Co-Located Virtual Machines

Side-channel attacks against cryptography keys have, until now, been limited to physical machines. Researchers have long made accurate determinations about crypto keys by studying anything from variations in power consumption to measuring how long it takes for a computation to complete. A team of...

Debian DSA-2548-1 : tor - several vulnerabilities

Several vulnerabilities have been discovered in Tor, an online privacy tool. - CVE-2012-3518 Avoid an uninitialised memory read when reading a vote or consensus document that has an unrecognized flavour name. This could lead to a remote crash, resulting in denial of service. - CVE-2012-3519 Try t...

CRIME Attack Uses Compression Ratio of TLS Requests as Side Channel to Hijack Secure Sessions

The new attack on TLS developed by researchers Juliano Rizzo and Thai Duong takes advantage of an information leak in the compression ratio of TLS requests as a side channel to enable them to decrypt the requests made by the client to the server. This, in turn, allows them to grab the user’s logi...

CVE-2012-3519

routerlist.c in Tor before 0.2.2.38 uses a different amount of time for relay-list iteration depending on which relay is chosen, which might allow remote attackers to obtain sensitive information about relay selection via a timing side-channel attack...
