Description


Multiple vulnerabilities have been reported in Wireshark, which can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a user's system.

1) NULL pointer dereference errors when reading certain packet information can be exploited to cause a crash.

2) An error within the RLC dissector can be exploited to cause a buffer overflow via a specially crafted RLC packet capture file.

Successful exploitation of this vulnerability may allow execution of arbitrary code.

3) An error within the "lanalyzer_read()" function (wiretap/lanalyzer.c) when parsing LANalyzer files can be exploited to cause a heap-based buffer underflow.

Successful exploitation of this vulnerability may allow execution of arbitrary code.

NOTE: A weakness within the file parser, which can lead to a crash when handling capture files has also been reported.

The vulnerabilities are reported in versions 1.4.0 through 1.4.10 and 1.6.0 through 1.6.4.


Solution:
Update to version 1.4.11 or 1.6.5.
