|Gentoo Linux Security Advisory
Title: Uim: Privilege escalation vulnerability (GLSA 200510-03)
Date: October 04, 2005
Updated: May 22, 2006
Under certain conditions, applications linked against Uim suffer from a privilege escalation vulnerability.
Uim is a multilingual input method library which provides secure and useful input method for all languages.
Vulnerable: < 0.4.9.1
Unaffected: >= 0.4.9.1
Architectures: All supported architectures
Masanari Yamamoto discovered that Uim uses environment variables incorrectly. This bug causes a privilege escalation if setuid/setgid applications are linked to libuim. This bug 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.
There is no known workaround at this time.
All Uim users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-i18n/uim-0.4.9.1"
