Description


Two vulnerabilities have been reported in various Novell products, which can be exploited by malicious people to compromise a vulnerable system.

1) A boundary error exists in the HTTP Protocol Stack (httpstk) component of iMonitor within the "BuildRedirectURL()" function when processing "Host" HTTP headers. This can be exploited to cause a stack-based buffer overflow via a specially crafted request with an overly long "Host" header (more than 64 bytes).

2) A boundary error exists within the user authentication component of Netmail when processing usernames. This can be exploited to cause a stack-based buffer overflow via a specially crafted username.

Successful exploitation allows execution of arbitrary code.

The following products are affected by one or both of the vulnerabilities:
- Netmail 3.5.2
- Novell eDirectory 8.8.1


Solution:
Apply fixes.
