Date Reported:
20 Dec 2016
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 848830.
In Mitre's CVE dictionary: CVE-2015-8979.
More information:

At several places in the code a wrong length of ACSE data structures received over the network can cause overflows or underflows when processing those data structures. Related checks have been added at various places in order to prevent such (possible) attacks. Thanks to Kevin Basista for the report.

The bug will indeed affect all DCMTK-based server applications that accept incoming DICOM network connections that are using the dcmtk-3.6.0 and earlier versions.


For Debian 7 Wheezy, these problems have been fixed in version 3.6.0-12+deb7u1.

We recommend that you upgrade your dcmtk packages.
