Multiple bugs were found in the code handling fax page reception in JPEG format that allow arbitrary writes to an uninitialized pointer by remote parties dialing in. When processing an specially crafted input, the issue could lead to remote code execution. HylaFAX versions 6.0.6 and 5.6.0 are affected.
