DESCRIPTION:
Masanari Yamamoto has reported a vulnerability in uim, which
potentially can be exploited by malicious, local users to gain
escalated privileges.

The vulnerability is caused due to the incorrect use of environment
variables by several functions in "uim/uim-custom.c". This can be
exploited to gain escalated privileges when libuim is linked against
an application running setuid/setgid (e.g. "immodule for Qt" enabled
Qt).

The vulnerability has been reported in stable versions prior to
0.4.9.1, and in development versions prior to 0.5.0.1.

SOLUTION:
Update to version 0.4.9.1.
