EPSS 27.87%
Description
Integer underflow in OpenSSL before 0.9.8x, 1.0.0 before 1.0.0j, and 1.0.1 before 1.0.1c, when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted TLS packet that is not properly handled during a certain explicit IV calculation.

Remediation
Red Hat statement
This issue did not affect the versions of openssl as shipped with Red Hat Enterprise Linux 3 and 4. The openssl versions in Red Hat Enterprise Linux 5 and 6 were partially affected, as they support DTLS, but they do not support TLS 1.1 and TLS 1.2. This issue was addressed in Red Hat Enterprise Linux 5 and 6 via RHSA-2012:0699.
