Name: Wireshark memory alignment flaw
Date: May 21, 2012
Versions affected: 1.4.0 to 1.4.12, 1.6.0 to 1.6.7
Fixed in: 1.4.13, 1.6.8
Wireshark could crash on SPARC or Itanium processors due to misaligned memory. Discovered by Klaus Heckelmann.
It may be possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.
Upgrade to Wireshark 1.4.13, 1.6.8 or later.
