Debian Security Advisory DSA 655-1 security@debian.org

---------------------------------------------------------------------------

Package : zhcon
Vulnerability : missing privilege release
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2005-0072

Erik Sjölund discovered that zhcon, a fast console CJK system using the Linux framebuffer, accesses a user-controlled configuration file with elevated privileges. Thus, it is possible to read arbitrary files.

For the stable distribution (woody) this problem has been fixed in version 0.2-4woody3.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your zhcon package.
