Vulnerability Name:

CVE-2013-1618 (CCN-81909)

Assigned:2013-02-06
Published:2013-02-06
Updated:2013-03-08
Summary:The TLS implementation in Opera before 12.13 does not properly consider timing side-channel attacks on a MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
