Discussion

ProZilla Multiple Remote Buffer Overflow Vulnerabilities

It is reported that multiple buffer overflow vulnerabilities exist in ProZilla. These issues are due to a failure of the application to properly bounds check user-supplied input prior to copying it into fixed sized memory buffers.

These vulnerabilities allow remote attackers to execute arbitrary code in the context of a user running the affected application. A victim user is required to attempt to download files from an attacker-controlled server for an exploit to succeed.
