[hylafax-devel] Security patches for hylafax-v4.0pl2
I had a bit of time last weekend, so in the interest of patching the setuid
uucp buffer overflow in faxalter and getting the FreeBSD/OpenBSD port
current, I did a beginnings of a security audit on hylafax-v4.0pl2. Below
are patches for various unbounded string copies in the source.
The functions that I checked are:
strcpy
strcat
sprintf
vsprintf
There were a few instances of possible unbounded character string copies
that I did not alter. The fix was non-obvious and buried deep in support
functions. I also did not check any possible race conditions.
What is the status of hylafax-v4.0pl2? Is any work being done on it? Is
another patch level forthcoming? Or is the effort being targeted to
4.1beta? Would my time be better spent looking at the latter?
