Name: Multiple problems in Wireshark

Docid: wnpa-sec-2008-05

Date: September 3, 2008

Affected versions: 0.9.7 up to and including 1.0.2

Fixed versions: 1.0.3



Wireshark 1.0.3 fixes the following vulnerabilities:

  • The NCP dissector was susceptible to a number of problems, including buffer overflows and an infinite loop. (Bug )
    Versions affected: 0.9.7 to 1.0.2
  • Wireshark could crash while uncompressing zlib-compressed packet data. (Bug )
    Versions affected: 0.10.14 to 1.0.2
  • Wireshark could crash while reading a Tektronix .rf5 file.
    Versions affected: 0.99.6 to 1.0.2


It may be possible to make Wireshark crash by injecting a series of malformed packets onto the wire or by convincing someone to read a malformed packet trace file.


Upgrade to Wireshark 1.0.3 or later. Due to the nature of these bugs, there is no workaround for previous versions.
