Título:	RedHat Security Advisory RHSA-2003:249
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2003:249. The GNU libc package (known as glibc) contains the standard C libraries used by applications. A bug in the getgrouplist function can cause a buffer overflow if the size of the group list is too small to hold all the user's groups. This overflow can cause segmentation faults in user applications, which may have security implications, depending on the application in question. This vulnerability exists only when an administrator has placed a user in a number of groups larger than that expected by an application. Therefore, there is no risk in instances where users are members of few groups. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0689 to this issue. In addition, a number of other bugs in glibc have been fixed: - - An error prevented gdb from correctly debugging programs linked to libpthread. - - A race condition existed in the malloc routine for IA64 platforms, which could cause memory corruption. - - An error in pthread_spinlocks prevents spinlocks from functioning correctly on IA64 platforms. All users should upgrade to these errata packages, which contain patches to the glibc libraries correcting these issues. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2003-249.html Risk factor : High CVSS Score: 7.5
