CVE-2002-1568: OpenSSL

Medium severity, CVSS 5.0. EPSS: 2.8% chance of exploitation in the next 30 days.

OpenSSL 0.9.6e uses assertions when detecting buffer overflow attacks instead of less severe mechanisms, which allows remote attackers to cause a denial of service (crash) via certain messages that cause OpenSSL to abort from a failed assertion, as demonstrated using SSLv2 CLIENT_MASTER_KEY messages, which are not properly handled in s2_srvr.c.

Affected products

• OpenSSL OpenSSL: version 0.9.6e only
