Release Date February 28, 2005
Latest Revision February 28, 2005: 01

Package Vulnerable versions Unaffected versions Architecture(s)

Related bugreports: #82678


Under certain conditions, applications linked against uim suffer from a privilege escalation vulnerability.

2.  Impact Information


uim is a simple, secure and flexible input method library.


Takumi Asaki discovered that uim insufficiently checks environment variables. setuid/setgid applications linked against libuim could end up executing arbitrary code. This vulnerability only affects immodule-enabled Qt (if you build Qt 3.3.2 or later versions with USE="immqt" or USE="immqt-bc").


A malicious local user could exploit this vulnerability to execute arbitrary code with escalated privileges.

3.  Resolution Information


There is no known workaround at this time.


All uim users should upgrade to the latest available version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-i18n/uim-"
