Details

Havoc Pennington discovered that the D-Bus daemon did not correctly
validate certain security policies. If a local user sent a specially
crafted D-Bus request, they could bypass security policies that had a
"send_interface" defined. (CVE-2008-0595)

It was discovered that the D-Bus library did not correctly validate
certain corrupted signatures. If a local user sent a specially crafted
D-Bus request, they could crash applications linked against the D-Bus
library, leading to a denial of service. (CVE-2008-3834)
