-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-98.173 -- Red Hat Linux Bulletin SECURITY: new libc 5 packages available 13 November 1998 =========================================================================== Red Hat Software, Inc. has released the following advisory concerning a buffer overflow vulnerability in the libc 5 packages shipped with Red Hat Linux running on Intel and Sparc architectures. - --------------------------BEGIN INCLUDED TEXT------------------- - -----BEGIN PGP SIGNED MESSAGE----- A buffer overflow has been identified in all versions of the libc 5 packages shipped with Red Hat Linux. The most affected systems are those that are libc 5 based (Red Hat Linux 4.2 and older). Only Intel and Sparc architectures are affected. The Red Hat Linux 5.x releases are glibc (libc 6) based, and Red Hat does not ship any binaries linked against libc 5 that might be used for compromising the system's security. However, Red Hat Linux 5.x releases do include for backwards compatibility a package containg a vulnerable library.
