DSA-866-1 mozilla Detailed Explanation for this Vulnerability Assessment Several security-related problems have been discovered in Mozilla and derived programs. The Common Vulnerabilities and Exposures project identifies the following problems: Tom Ferris discovered a bug in the IDN hostname handling of Mozilla that permits remote attackers to cause a denial of service and possibly execute arbitrary code via a hostname with dashes. A buffer overflow permits remote attackers to execute arbitrary code via an XBM image file that ends in a large number of spaces instead of the expected end tag. Mats Palmgren discovered a buffer overflow in the Unicode string parser that permits a specially crafted Unicode sequence to overflow a buffer and cause arbitrary code to be executed. Remote attackers could spoof HTTP headers of XML HTTP requests via XMLHttpRequest and possibly use the client to exploit vulnerabilities in servers or proxies. Remote attackers could spoof DOM objects via an XBL control that implements an internal XPCOM interface. Georgi Guninski discovered an integer overflow in the JavaScript engine that might permit remote attackers to execute arbitrary code. Remote attackers could execute Javascript code with chrome rights via an about: page such as about:mozilla. Remote attackers could spawn windows without user interface components such as the address and status bar that could be used to conduct spoofing or phishing attacks. Peter Zelezny discovered that shell metacharacters are not properly escaped when they are passed to a shell script and permit the execution of arbitrary commands, e.g. when a malicious URL is automatically copied from another program into Mozilla as default browser. For the stable distribution (sarge) these problems have been fixed in version 1.7.8-1sarge3. For the unstable distribution (sid) these problems have been fixed in version 1.7.12-1. We recommend that you upgrade your mozilla package.
