Description:
Marco Ortisi has reported a vulnerability in Squid, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to insufficient validation of negative values in the function "ntlm_fetch_string()" in "lib/ntlmauth.c". This can be exploited by sending a specially crafted NTLMSSP packet, which can cause the NTLM helpers provided by Squid to crash.
Successful exploitation requires that NTLM authentication is enabled.
The vulnerability has been reported in version 2.5.
