ID de Prueba: | 1.3.6.1.4.1.25623.1.0.70023 |
Categoría: | Red Hat Local Security Checks |
Título: | RedHat Security Advisory RHSA-2011:1104 |
Resumen: | NOSUMMARY |
Descripción: | Description: The remote host is missing updates announced in advisory RHSA-2011:1104. The libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. A buffer overflow flaw was found in the way libpng processed certain PNG image files. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-2690) Note: The application behavior required to exploit CVE-2011-2690 is rarely used. No application shipped with Red Hat Enterprise Linux behaves this way, for example. An uninitialized memory read issue was found in the way libpng processed certain PNG images that use the Physical Scale (sCAL) extension. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash. (CVE-2011-2692) Users of libpng should upgrade to these updated packages, which contain backported patches to correct these issues. All running applications using libpng must be restarted for the update to take effect. 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-2011-1104.html Risk factor : High CVSS Score: 6.8 |
