CVE-2007-1739: IBM Lotus Domino

High severity, CVSS 7.8. EPSS: 3.4% chance of exploitation in the next 30 days.

Heap-based buffer overflow in the LDAP server in IBM Lotus Domino before 6.5.6 and 7.x before 7.0.2 FP1 allows remote attackers to cause a denial of service (crash) via a long, malformed DN request, which causes only the lower 16 bits of the string length to be used in memory allocation.

Affected products

• IBM Lotus Domino: version 7.0 only; version 7.0.1 only; version 7.0.2 only
