DESCRIPTION:
Luigi Auriemma has discovered multiple vulnerabilities in Cytel
StatXact, Cytel LogXact, and Cytel CrossOver, which can be exploited
by malicious people to compromise a user's system.
1) A boundary error in Cytel Studio (CeCEDll.dll) when processing
Data files (".cy3" and ".cyl") can be exploited to cause a
stack-based buffer overflow via a specially crafted file.
2) An integer overflow error in Cytel Studio when processing Data
files (".cy3" and ".cyl") can be exploited to cause a heap-based
buffer overflow via a specially crafted file.
3) A boundary error in Cytel Studio (cbf.exe) when processing Submit
files (".cyb") can be exploited to cause a stack-based buffer
overflow via an overly long string assigned to the "USE" command.
Successful exploitation of these vulnerabilities allows execution of
arbitrary code, but requires tricking a user into opening a malicious
file.
The vulnerabilities are confirmed in version 9.0.0. Other versions
may also be affected.
SOLUTION:
Do not open files from untrusted sources.
