New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated libtiff packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.
The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files.
Multiple integer overflow flaws, leading to a buffer overflow, were discovered in libtiff. An attacker could use these flaws to create a specially crafted TIFF file that, when opened, would cause an application linked against libtiff to crash or, possibly, execute arbitrary code. (CVE-2010-1411)
Multiple input validation flaws were discovered in libtiff. An attacker could use these flaws to create a specially crafted TIFF file that, when opened, would cause an application linked against libtiff to crash. (CVE-2010-2481, CVE-2010-2483, CVE-2010-2595, CVE-2010-2597)
Red Hat would like to thank Apple Product Security for responsibly reporting the CVE-2010-1411 flaw, who credit Kevin Finisterre of digitalmunition.com for the discovery of the issue.
All libtiff users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. All running applications linked against libtiff must be restarted for this update to take effect.
SolutionUpdate the affected libtiff and / or libtiff-devel packages.
