Several denial of service vulnerabilities have been discovered in polipo, a small, caching web proxy. The Common Vulnerabilities and Exposures project identifies the following problems :
CVE-2009-3305 A malicous remote server could cause polipo to crash by sending an invalid Cache-Control header.
CVE-2009-4143 A malicous client could cause polipo to crash by sending a large Content-Length value.
This upgrade also fixes some other bugs that could lead to a daemon crash or an infinite loop and may be triggerable remotely.
