Title: SpamProbe Remote Denial of Service Vulnerability
Severity: MODERATE
Description:
SpamProbe is a spam detection program that uses a Bayesian analysis of the frequencies of terms used in the email. It is available for the Linux operating system.
A denial of service vulnerability exists in SpamProbe. The problem occurs in a regular expression used by the removeHTMLFromText() function, which is located in MessageFactory.cc.
When SpamProbe attempts to parse HTML located in an emails an issue may occur on some operating systems which could cause SpamProbe to crash. The problem reportedly occurs when attempting to parse newline characters (\n) located within HTML <href> tags.
This issue could be exploited by an attacker to disable a victim's spam filter. Any subsequent unsolicited email messages sent to the victim would be successfully delivered.
This condition has been reported to occur on RedHat 8.0. It is not yet known whether SpamProbe is prone to this issue when running on other distributions or operating systems.
