Two bugs have been discovered in qpopper, an enhanced Post Office Protocol (POP3) server. The Common Vulnerability and Exposures project identifies the following problems: CAN-2005-1151 Jens Steube discovered that while processing local files owned or provided by a normal user privileges weren't dropped, which could lead to the overwriting or creation of arbitrary files as root. CAN-2005-1152 The upstream developers noticed that qpopper could be tricked to creating group- or world-writable files. For the stable distribution (woody) these problems have been fixed in version 4.0.4-2.woody.5. For the testing distribution (sarge) these problems have been fixed in version 4.0.5-4sarge1. For the unstable distribution (sid) these problems will be fixed in version 4.0.5-4sarge1. We recommend that you upgrade your qpopper package.
