To: [email protected]Subject: Buffer overflow in Xprt
There is a buffer overflow in the postscript backend of the
Xprint server: look at the S_OutStr() function in the file psout.c.
A user-supplied variable-lenght string is stored in a 512 sized buffer.
This bug is present in version R6, public-patch-3 and later.
WORKAROUND: do not run the Xprt server.
FIX: make the function malloc() a buffer big enough and recompile.
xfree86 and opengroup have been notified a while ago.
