Description: Some vulnerabilities have been reported in VLC Media Player, which can be exploited by malicious, local users to gain escalated privileges, and by malicious people to potentially compromise a user's system.
1) An input validation error exists in the processing of Speex headers.
For more information:
SA29727
2) The problem is that the application executes e.g. the "vlc_entry__0_8_6" symbol from libraries with a file name matching the "lib*_plugin.so" pattern, placed in the "modules" or "plugins" subdirectories of the current working directory. This can be exploited to execute arbitrary code with escalated privileges by tricking a user into playing a file placed in a directory containing specially crafted libraries.
The vulnerabilities are reported in version 0.8.6f. Other versions may also be affected.
Solution: Fixed in the GIT repository.
