Description Jan Lieskovsky 2013-05-20 16:32:40 UTC

Originally, CVE-2013-2486 (bug #CVE-2013-2486) and CVE-2013-2487 (bug #CVE-2013-2487) identifiers have been assigned to a denial of service flaw (excessive CPU consumption and infinite loop) in the RELOAD dissector of Wireshark.

Later it was reported:
  [1] https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8546#c0

that despite being officially announced the complete patch has not been applied upstream (r47808 was, but r47805 was not). Original r47805 patch has been now applied upstream as revision:
  [2] http://anonsvn.wireshark.org/viewvc?view=revision&revision=48677

and whole issue has been corrected in Wireshark 1.8.7 version.

Relevant upstream bug reports:
[3] https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8364
