Hashcash Remote Heap Buffer Overflow Vulnerability
A buffer-overflow vulnerability exists in the generic C implementation of Hashcash. This issue is due to the software's failure to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer. This issue may allow attackers to execute arbitrary machine code in the context of the affected application. This may facilitate the remote compromise of affected computers. Hashcash versions prior to 1.21 are vulnerable to this issue. |
