Multiple vulnerabilities in D-Bus might allow an attacker to overwrite files with a fixed filename in arbitrary directories or conduct a symlink attack.
|Package||sys-apps/dbus on all architectures|
|Affected versions||< 1.10.18|
|Unaffected versions||>= 1.10.18|
D-Bus is a message bus system which processes can use to talk to each other.
Multiple vulnerabilities have been discovered in D-Bus. Please review the original report referenced below for details.
An attacker could possibly overwrite arbitrary files named “once” with content not controlled by the attacker.
A local attacker could perform a symlink attack against D-Bus’ test suite.
There is no known workaround at this time.
All D-Bus users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.10.18"
