Categoría:	Red Hat Local Security Checks
Título:	RedHat Security Advisory RHSA-2003:310
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2003:310. The fileutils package contains several basic system utilities. One of these utilities is the ls program, which is used to list information about files and directories. Georgi Guninski discovered a memory starvation denial of service vulnerability in the ls program. It is possible to make ls allocate a huge amount of memory by specifying certain command line arguments. This vulnerability is remotely exploitable through services like wu-ftpd, which pass user arguments to ls. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0854 to this issue. A non-exploitable integer overflow in ls has been discovered. It is possible to make ls crash by specifying certain command line arguments. This vulnerability is remotely exploitable through services like wu-ftpd, which pass user arguments to ls. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0853 to this issue. Users are advised to update to these erratum packages, which contain backported security patches that correct these vulnerabilities. These packages also add support for the O_DIRECT flag, which controls the use of synchronous I/O on file systems such as OCFS. 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-2003-310.html Risk factor : Medium CVSS Score: 5.0
