You didn't answer all our questions yet, specifically which was the
vulnerable function. I was hoping to get some feel for whether this could be
exploited remotely, e.g. by uploading a long file to an ftp server, and
whether it could be used to increase privilege, by triggering in a cygwin
The answers to those questions would determine my suggested response. If
any of them were 'yes', I would suggest we delete the affected versions from
the sourceware repository and place an announcement on the cygwin.com front
page, co-ordinated with your advisory. If not, I would suggest that it would
be appropriate to just release your advisory to the mailing list.
However, Corinna is the responsible maintainer, so we should wait for her
BTW, it's not clear from your subject line: cygwin1.dll < 1.5.22, or
cygwin1.dll <= 1.5.22? Which was the first fixed version?
Can't think of a witty .sigline today....
