Description: Debian has reported a vulnerability in webfs, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error in the handling of Request-URI. This can be exploited to cause a buffer overflow by sending an overly long, specially crafted HTTP request. Successful exploitation allows execution of arbitrary code on a vulnerable system with the privileges of webfs. Solution: The vulnerability has been fixed in webfs version 1.18 and later.
