Related bugreports: #504100


A stack-based buffer overflow vulnerability has been found in udisks, allowing a local attacker to possibly execute arbitrary code or cause Denial of Service.

2.  Impact Information


udisks is an abstraction for enumerating block devices and performing operations on them.


A stack-based buffer overflow can be triggered when udisks is given a long path name as a mount point.


A local attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.

3.  Resolution Information


There is no known workaround at this time.


All udisks 1.0 users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-fs/udisks-1.0.5:0"

All udisks 2.0 users should upgrade to the latest version:

Code Listing 3.2: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-fs/udisks-2.1.3"
