The remote host is missing updates announced in
advisory RHSA-2008:0146.
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.
