Test ID:	1.3.6.1.4.1.25623.1.0.112920
Category:	Denial of Service
Title:	OpenSSL: Denial of Service in ASN.1 parsing (CVE-2003-0851) - Linux
Summary:	OpenSSL is prone to a denial of service (DoS) vulnerability.
Description:	Summary: OpenSSL is prone to a denial of service (DoS) vulnerability. Vulnerability Insight: A flaw in OpenSSL would cause certain ASN.1 sequences to trigger a large recursion. On platforms such as Windows this large recursion cannot be handled correctly and so the bug causes OpenSSL to crash. Vulnerability Impact: A remote attacker could exploit this flaw if they can send arbitrary ASN.1 sequences which would cause OpenSSL to crash. This could be performed for example by sending a client certificate to a SSL/TLS enabled server which is configured to accept them. Affected Software/OS: OpenSSL 0.9.6k. Solution: Update to version 0.9.6l or later. See the references for more details. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
