[GLSA-200409-28] GTK+ 2, gdk-pixbuf: Multiple image decoding vulnerabilities |

GTK+ 2, gdk-pixbuf: Multiple image decoding vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200409-28 (GTK+ 2, gdk-pixbuf: Multiple image decoding vulnerabilities) A vulnerability has been discovered in the BMP image preprocessor (CVE-2004-0753). Furthermore, Chris Evans found a possible integer overflow in the pixbuf_create_from_xpm() function, resulting in a heap overflow (CVE-2004-0782). He also found a potential stack-based buffer overflow in the xpm_extract_color() function (CVE-2004-0783). A possible integer overflow has also been found in the ICO decoder. Impact With a specially crafted BMP image a possible hacker could cause an affected application to enter an infinite loop when that image is being processed. Also, by making use of specially crafted XPM or ICO images a possible hacker could trigger the overflows, which potentially permits the execution of arbitrary code. Workaround There is no known workaround at this time.
