Vulnerability from csaf_redhat - Published: 2003-01-30 19:35 - Updated: 2025-11-21 17:25
Summary
Red Hat Security Advisory: glibc security update
Severity
Moderate
Notes
Topic: Updated glibc packages are available to fix a buffer overflow in the resolver.
Details: The GNU C library package, glibc, contains standard libraries used by multiple programs on the system. A read buffer overflow vulnerability exists in the glibc resolver code in versions of glibc up to and including 2.2.5. The vulnerability is triggered by DNS packets larger than 1024 bytes and can cause applications to crash. In addition to this, several non-security related bugs have been fixed, the majority for the Itanium (IA64) platform. All Red Hat Linux Advanced Server users are advised to upgrade to these errata packages which contain a patch to correct this vulnerability.

CVE-2002-1146

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).
