Description:
Two vulnerabilities have been discovered in Helix Player, which potentially can be exploited by malicious people to compromise a user's system.
1) A format string error exists when displaying the invalid-handle error message. This may be exploited to execute arbitrary code via a specially crafted ".rp" (RealPix) file that contains format-string specifiers in the "handle" attribute of the "image" tag. The ".rt" file format may also be affected.
2) A format string error exists when displaying the "missing XML tag end" error message. This may be exploited to execute arbitrary code via a specially crafted ".rp" file that contains format-string specifiers in the attributes of the "head" tag.
Successful exploitation requires that the user is e.g. tricking into opening or following a link to a malicious ".rp" file.
The vulnerabilities have been confirmed in Helix Player 1.0.5.757 (gold), and affects only the Linux/Unix platforms. Prior versions may also be affected.
Note: Exploit code for vulnerability #1 is publicly available.
Solution:
Update to version 1.0.6.
