Título:	RedHat Security Advisory RHSA-2005:377
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2005:377. The sharutils package contains a set of tools for encoding and decoding packages of files in binary or text format. A stack based overflow bug was found in the way shar handles the -o option. If a user can be tricked into running a specially crafted command, it could lead to arbitrary code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1772 to this issue. Please note that this issue does not affect Red Hat Enterprise Linux 4. Two buffer overflow bugs were found in sharutils. If an attacker can place a malicious 'wc' command on a victim's machine, or trick a victim into running a specially crafted command, it could lead to arbitrary code execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1773 to this issue. A bug was found in the way unshar creates temporary files. A local user could use symlinks to overwrite arbitrary files the victim running unshar has write access to. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0990 to this issue. All users of sharutils should upgrade to this updated package, which includes backported fixes to correct 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-2005-377.html Risk factor : High CVSS Score: 7.5
