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.
