The artswrapper part of aRts allows local users to execute arbitrary code with elevated privileges.
|Package||kde-base/arts on all architectures|
|Affected versions||< 3.5.2-r1|
|Unaffected versions||>= 3.5.2-r1
revision >= 3.4.3-r1
aRts is a real time modular system for synthesizing audio used by KDE. artswrapper is a helper application used to start the aRts daemon.
artswrapper fails to properly check whether it can drop privileges accordingly if setuid() fails due to a user exceeding assigned resource limits.
Local attackers could exploit this vulnerability to execute arbitrary code with elevated privileges. Note that the aRts package provided by Gentoo is only vulnerable if the artswrappersuid USE-flag is enabled.
There is no known workaround at this time.
All aRts users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose kde-base/arts
