ID de Prueba:	1.3.6.1.4.1.25623.1.0.52118
Categoría:	Red Hat Local Security Checks
Título:	RedHat Security Advisory RHSA-2005:261
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2005:261. The GNU libc packages (known as glibc) contain the standard C libraries used by applications. Flaws in the catchsegv and glibcbug scripts were discovered. A local user could utilize these flaws to overwrite files via a symlink attack on temporary files. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0968 and CVE-2004-1382 to these issues. It was discovered that the use of LD_DEBUG and LD_SHOW_AUXV were not restricted for a setuid program. A local user could utilize this flaw to gain information, such as the list of symbols used by the program. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1453 to this issue. This erratum also addresses the following bugs in the GNU C Library: - - Now avoids calling sigaction (SIGPIPE, ...) in syslog implementation - - Fixed poll on Itanium - - Now allows setenv/putenv in shared library constructors Users of glibc are advised to upgrade to these erratum packages that remove the unecessary glibcbug script and contain backported patches to correct these other 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-2005-261.html Risk factor : Medium CVSS Score: 2.1
