Date:	10/04/2005
Bugs:	#107748
ID:	200510-03

Synopsis

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

Background

Uim is a multilingual input method library which provides secure and useful input method for all languages.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-i18n/uim	< 0.4.9.1	>= 0.4.9.1	All supported architectures

Description

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").

Impact

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

Workaround

There is no known workaround at this time.

Resolution

All Uim users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-i18n/uim-0.4.9.1"
