Plaintext-recovery attack vulnerability in Opera via statistical analysis of timing data for crafted packets (dpkg)ID: oval:org.secpod.oval:def:9316 | Date: (C)2013-02-19 (M)2022-10-10 |
Class: VULNERABILITY | Family: unix |
The host is installed with Opera before 12.13 and is prone to plaintext-recovery attack vulnerability. A flaw is present in the application, which does not properly consider timing side-channel attacks on a MAC check operation during the processing of malformed CBC padding. Successful exploitation allows attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets.
