Several vulnerabilities have been found in the Iceape internet suite, an unbranded version of Seamonkey:
Benoit Jacob, Jesse Ruderman, Christian Holler, and Bill McCloskey identified several memory safety problems that may lead to the execution of arbitrary code.
Abhishek Arya discovered a use-after-free problem in nsDocument::AdoptNode that may lead to the execution of arbitrary code.
For the stable distribution (squeeze), this problem has been fixed in version 2.0.11-14.
For the unstable (sid) and testing (wheezy) distribution, this problem will be fixed soon.
We recommend that you upgrade your iceape packages.
