Multiple format string vulnerabilities were discovered in neon, an HTTP and WebDAV client library. These vulnerabilities could potentially be exploited by a malicious WebDAV server to execute arbitrary code with the privileges of the process using libneon.
For the current stable distribution (woody) these problems have been fixed in version 0.19.3-2woody3.
For the unstable distribution (sid), these problems have been fixed in version 0.24.5-1.
We recommend that you update your neon package.
