[GLSA-200511-14] GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities |

GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200511-14 (GTK+ 2, GdkPixbuf: Multiple XPM decoding vulnerabilities) iDEFENSE reported a possible heap overflow in the XPM loader (CVE-2005-3186). Upon further inspection, Ludwig Nussel discovered two additional issues in the XPM processing functions : an integer overflow (CVE-2005-2976) that affects only gdk-pixbuf, and an infinite loop (CVE-2005-2975). Impact Using a specially crafted XPM image a possible hacker could cause an affected application to enter an infinite loop or trigger the overflows, potentially permiting the execution of arbitrary code. Workaround There is no known workaround at this time.
