CVSSv3.1: 4.6 [CVSS:3.1/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2009-1378

CWE-ID: CWE-399 - Resource Management Errors

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka "DTLS fragment handling memory leak."

Mitigation

Install update from vendor's website.

Vulnerable software versions

OpenSSL: 0.9.0b - 0.9.8k
