CVE-2002-0684: GNU Glibc

High severity, CVSS 7.5. EPSS: 5.9% chance of exploitation in the next 30 days.

Buffer overflow in DNS resolver functions that perform lookup of network names and addresses, as used in BIND 4.9.8 and ported to glibc 2.2.5 and earlier, allows remote malicious DNS servers to execute arbitrary code through a subroutine used by functions such as getnetbyname and getnetbyaddr.

Affected products

• GNU Glibc: up to and including 2.2.5
• ISC BIND: version 4.9.8 only
