The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-3305 A malicous remote sever 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. For the stable distribution (lenny), these problems have been fixed in version 1.0.4-1+lenny1. For the testing distribution (squeeze) and the unstable distribution (sid), these problems have been fixed in version 1.0.4-3. We recommend that you upgrade your polipo packages.
