CVE-2013-6450

openssl: crash in DTLS renegotiation after packet loss

Published Jan 1, 2014 CVSS 2.0 · 5.8 Medium EPSS 15.4% KEV · Not listed
Description
The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c.
