Description
The FESTAHES_Load function in pce/hes.c in Festalon 0.5.0 through 0.5.5 allows user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a negative LoadAddr value in a HES file, which is used as an offset in a memcpy operation and leads to a buffer underflow.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
