Description:
Multiple vulnerabilities have been reported in Ethereal, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
1) Various types of errors including NULL pointer dereference errors, divide by zero error, infinite loop errors, and boundary errors exist in a multitude of protocol dissectors.
2) A boundary error in the "unicode_to_bytes()" function of the SRVLOC (Service Location Protocol) dissector can be exploited to cause a buffer overflow via a specially crafted TCP packet with source and destination port set to 427/tcp.
3) Ethereal Windows installer ships with a vulnerable version of the PCRE library.
For more information:
SA16502
Successful exploitation causes Ethereal to stop responding, exhaust system memory, crash, or execute arbitrary code.
The vulnerabilities have been reported in versions 0.7.7 through 0.10.12.
