[DLA 754-1] tor security update

Package : tor
Version : 0.2.4.27-3
CVE ID : CVE-2016-1254
Debian Bug : #848847

It was discovered that Tor, a connection-based low-latency anonymous
communication system, may read one byte past a buffer when parsing
hidden service descriptors. This issue may enable a hostile hidden
service to crash Tor clients depending on hardening options and malloc
implementation.

For Debian 7 "Wheezy", these problems have been fixed in version
0.2.4.27-3.

We recommend that you upgrade your tor packages.

[DLA 755-1] dcmtk security update

Package : dcmtk
Version : 3.6.0-12+deb7u1
CVE ID : CVE-2015-8979
Debian Bug : 848830


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.
