What is CVE-2002-1146?
CVE-2002-1146 is a medium-severity memory corruption vulnerability in Gnu Glibc, published on 1 Sep 2004. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash).
