Exploitation vector: Network

Exploit availability: No

Vulnerable software:
OpenSSL

Vendor: OpenSSL Software Foundation

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to memory leak within 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 remote attacker can perform a denial of service attack.

Mitigation
Install update from vendor's website.

Vulnerable software versions

OpenSSL: 0.9.8y - 0.9.8p, 1.0.0g - 1.0.0, 1.0.1c - 1.0.1
