CVE-2005-2705

Multiple vulnerabilities exist in the mozilla-thunderbird package. A buffer overflow was discovered in the XBM image handler. By tricking an user into opening a specially crafted XBM image, an attacker could exploit this to execute arbitrary code with the user's privileges. Mats Palmgren discovered a buffer overflow in the Unicode string parser. Unicode strings that contained zero-width non-joiner characters caused a browser crash, which could possibly even exploited to execute arbitrary code with the user's privileges. Georgi Guninski reported an integer overflow in the JavaScript engine. This could be exploited to run arbitrary code under some conditions. Peter Zelezny discovered that URLs which are passed to Thunderbird on the command line are not correctly protected against interpretation by the shell. If Thunderbird is configured as the default handler for mailto: URLs, this could be exploited to execute arbitrary code with user privileges by tricking the user into clicking on a specially crafted URL (for example, in an email or chat client).
