Technical Description

Multiple vulnerabilities have been identified in SLMail Pro, which could be exploited by attackers to cause a denial of service or potentially compromise a vulnerable system.

The first issue is caused by a memory corruption error in the "webcontainer.exe" service when processing overly long URLs, which could be exploited by remote attackers to crash an affected application or potentially execute arbitrary code.

The second vulnerability is caused by an input validation error in the "webcontainer.exe" service when processing overly long HTTP requests, which could be exploited to crash an affected application, creating a denial of service condition.

The third vulnerability is caused by an error when processing malformed packets sent to port 54/UDP, which could be exploited by attackers to crash an affected service, creating a denial of service condition.
