New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionUpdated Mozilla Thunderbird packages fix various vulnerabilities :
The run-mozilla.sh script, with debugging enabled, would allow local users to create or overwrite arbitrary files via a symlink attack on temporary files (CVE-2005-2353).
A bug in the way Thunderbird processes XBM images could be used to execute arbitrary code via a specially crafted XBM image file (CVE-2005-2701).
A bug in the way Thunderbird handles certain Unicode sequences could be used to execute arbitrary code via viewing a specially crafted Unicode sequence (CVE-2005-2702).
A bug in the way Thunderbird makes XMLHttp requests could be abused by a malicious web page to exploit other proxy or server flaws from the victim's machine; however, the default behaviour of the browser is to disallow this (CVE-2005-2703).
A bug in the way Thunderbird opens new windows could be used by a malicious web page to construct a new window without any user interface elements (such as address bar and status bar) that could be used to potentially mislead the user (CVE-2005-2707).
A bug in the way Thunderbird proceesed URLs on the command line could be used to execute arbitary commands as the user running Thunderbird;
this could be abused by clicking on a supplied link, such as from an instant messaging client (CVE-2005-2968).
Tom Ferris reported that Thunderbird would crash when processing a domain name consisting solely of soft-hyphen characters due to a heap overflow when IDN processing results in an empty string after removing non-wrapping chracters, such as soft-hyphens. This could be exploited to run or or install malware on the user's computer (CVE-2005-2871).
The updated packages have been patched to correct these issues.
