What is CVE-2013-1618?

The TLS implementation in the Opera web browser versions prior to 12.13 is vulnerable to timing side-channel attacks, particularly during malformed CBC padding processing. This vulnerability arises because the MAC check operation does not effectively consider timing discrepancies, enabling remote attackers to exploit this flaw. By conducting statistical analysis on timing data for specially crafted packets, attackers can potentially conduct distinguishing and plaintext-recovery attacks. This vulnerability highlights significant security weaknesses in the handling of TLS connections in the affected versions of the browser.
