Discussion

Sun Java Web Proxy Server Multiple Buffer Overflow Vulnerabilities

Sun Java System Web Proxy Server is prone to multiple buffer-overflow vulnerabilities because the application fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.

An attacker can exploit these issues to execute arbitrary code with superuser privileges, leading to the complete compromise of affected computers. Failed exploit attempts will result in a denial of service.

These issues affect Web Proxy Server 4.0.3; prior versions may also be affected.
