Description:
Two vulnerabilities have been reported in webfs, which can be exploited by malicious people to disclose the contents of arbitrary files or by malicious, local users to escalate their privileges.
It is possible to conduct a directory traversal attack by specifying ".." as a hostname when virtual hosting is enabled. This may disclose the contents of arbitrary files outside the web root.
There is a boundary error in "ls.c" when handling pathnames. This can be exploited to cause a buffer overflow by constructing an overly long, specially crafted pathname.
Successful exploitation may allow execution of arbitrary code with the privileges of the web server but requires that a malicious, local user has write privileges to a directory readable by the web server.
