SynopsisThe remote Debian host is missing a security-related update.
DescriptionWe experienced that the update for Mozilla Firefox from DSA 779-1 unfortunately was a regression in several cases. Since the usual praxis of backporting apparently does not work, this update is basically version 1.0.6 with the version number rolled back, and hence still named 1.0.4-*. For completeness below is the original advisory text :
Several problems have been discovered in Mozilla Firefox, a lightweight web browser based on Mozilla. The Common Vulnerabilities and Exposures project identifies the following problems :
- CAN-2005-2260 The browser user interface does not properly distinguish between user-generated events and untrusted synthetic events, which makes it easier for remote attackers to perform dangerous actions that normally could only be performed manually by the user.
It is possible for a remote attacker to execute a callback function in the context of another domain (i.e. frame).
By opening a malicious link in the sidebar it is possible for remote attackers to steal sensitive information.
Missing input sanitising of InstallVersion.compareTo() can cause the application to crash.
Remote attackers could steal sensitive information such as cookies and passwords from websites by accessing data in alien frames.
Remote attackers could modify certain tag properties of DOM nodes that could lead to the execution of arbitrary script or code.
The Mozilla browser family does not properly clone base objects, which allows remote attackers to execute arbitrary code.
SolutionUpgrade the Mozilla Firefox packages.
The old stable distribution (woody) is not affected by these problems.
For the stable distribution (sarge) these problems have been fixed in version 1.0.4-2sarge3.
