Описание
Memory leak in d1_both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service (memory consumption) via zero-length DTLS fragments that trigger improper handling of the return value of a certain insert function.
A flaw was discovered in the way OpenSSL handled DTLS packets. A remote attacker could use this flaw to cause a DTLS server or client using OpenSSL to crash or use excessive amounts of memory.
Отчет
This did not affect openssl packages in Red Hat Enterprise Linux 5 (based on upstream 0.9.8e) and openssl 1.0.0 packages in Red Hat Enterprise Linux 6 (i.e. packages released before RHBA-2013:1585, which rebased openssl from 1.0.0 to 1.0.1e). The issue was introduced upstream in versions 0.9.8o and 1.0.0a.
