Security researchers have identified multiple unpatched vulnerabilities in a widely-used content distribution package.

Tibco's SmartPGM FX multicasting software is prone to multiple remote vulnerabilities, including four stack-based buffer-overflow flaws, a format-string issue, and a potential denial of service bug.

Hackers might exploit these issues to execute arbitrary code or cause denial-of-service attacks, warns UK consultancy Information Risk Management (IRM).

IRM, which has a track record of discovering bugs in the software, is withholding details of the flaws pending the availability of patches from Tibco.

To date, there's no evidence that the bugs have being used in anger by hackers. Nonetheless, the discovery of the bugs illustrates a wider range of software packages than is commonly imagined can be subject to so-called zero-day vulnerabilities. ®
