A bug was discovered in ld.so that could allow local users to obtain root privileges. The dynamic loader, ld.so, is responsible for making shared libraries available within a program at run-time. Normally, a user is allowed to load additional shared libraries when executing a program; they can be specified with environment variables such as LD_PRELOAD. Because this is not acceptable for applications that are setuid root, ld.so normally removes these environment variables for setuid root programs. The discovered bug causes these environment variables to not be removed under certain circumstances. While setuid programs themselves are not vulnerable, external programs they execute can be affected by this problem. These updated packages contain a patch from Caldera Systems, Inc. that fixes this vulernability. It should be noted that as of yet there are no known exploits for this problem, but all users should update to these glibc packages.
