The remote Red Hat host is missing one or more security updates.
Updated gd packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. The gd package contains a graphics library used for the dynamic creation of images such as PNG and JPEG. Multiple issues were discovered in the gd GIF image-handling code. A carefully-crafted GIF file could cause a crash or possibly execute code with the privileges of the application using the gd library. (CVE-2006-4484, CVE-2007-3475, CVE-2007-3476) An integer overflow was discovered in the gdImageCreateTrueColor() function, leading to incorrect memory allocations. A carefully crafted image could cause a crash or possibly execute code with the privileges of the application using the gd library. (CVE-2007-3472) A buffer over-read flaw was discovered. This could cause a crash in an application using the gd library to render certain strings using a JIS-encoded font. (CVE-2007-0455) A flaw was discovered in the gd PNG image handling code. A truncated PNG image could cause an infinite loop in an application using the gd library. (CVE-2007-2756) A flaw was discovered in the gd X BitMap (XBM) image-handling code. A malformed or truncated XBM image could cause a crash in an application using the gd library. (CVE-2007-3473) Users of gd should upgrade to these updated packages, which contain backported patches which resolve these issues.
Update the affected gd, gd-devel and / or gd-progs packages.
