Description Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2006-11-07 00:50:48 UTC
Fixed: NTLM authentication doesn't work for NT-encoded passwords and may
  cause account blocking (reported by boris16 at tut.by)

CC'ing net-proxy

this does not really sound like a security issue, does it?

The only source file differences between 0.5.3 and 0.5.3a

This patch contains the only source file differences between 0.5.3 and 0.5.3a.
Comment 3 Alin Năstac (RETIRED) gentoo-dev 2006-11-09 06:45:03 UTC
I've bumped the version to 0.5.3a, but I don't understand the problem. 

In first case, 2 pointers are converted to unsigned, then substracted, then the result is casted to unsigned char.
In second case, 2 pointers are converted to (unsigned char*), then substracted, then the result is casted to unsigned char.

At first look, I don't see any difference between those 2 cases. 
Mike, can you explain it, please?
Comment 4 SpanKY gentoo-dev 2006-11-09 15:54:50 UTC
that change is what i requested

the diff you should be reviewing is 0.5.2 to 0.5.3a
Comment 5 Alin Năstac (RETIRED) gentoo-dev 2006-11-10 07:02:17 UTC
Doesn't look like a security issue to me. The only NTLM related change is in proxy.c file:
        "HTTP/1.0 407 Proxy Authentication Required\r\n"
-       "Proxy-Authenticate: basic realm=\"proxy\"\r\n"
        "Proxy-Authenticate: NTLM\r\n"
+       "Proxy-Authenticate: basic realm=\"proxy\"\r\n"
        "Proxy-Connection: close\r\n"

Alin/SpanKY any news on this one? Or is it INVALID?
Comment 7 Alin Năstac (RETIRED) gentoo-dev 2006-11-20 22:50:11 UTC
I've looked over the diff between 0.5.2 and 0.5.3 and I didn't found a security security issue in it. Ask Mike if he has knowledge of such issue (he isn't member of net-proxy team so it doesn't receive this comment on email).
Comment 8 Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2006-11-20 23:56:39 UTC
Thx Alin. SpanKY is on the security team, so he should be getting these as well.
Comment 9 SpanKY gentoo-dev 2006-11-28 17:31:27 UTC
not a security issue, thanks Alin for reviewing

i tend to read security lists in bulk ;)
