Description |
XDM in XFree86 contains a flaw that may allow a malicious user to perform a brute force attack. The issue is triggered when X server is complied without HasXdmXauth, which will cause the cookies to be generated by the "gettimeofday" function. A remote attacker can potentially guess the cookie values and gain unauthorized access to the system, resulting in a loss of integrity.
