-Subject: [PATCH] telnetd/utility.c: Fix buffer overflow in netoprintf
-
-As per man page of vsnprintf, when formated
-string size is greater than "size"(2nd argument),
-then vsnprintf returns size of formated string,
-not "size"(2nd argument).
-
-netoprintf() was not handling a case where
-return value of vsnprintf is greater than
-"size"(2nd argument), results in buffer overflow
-while adjusting "nfrontp" pointer to point
-beyond "netobuf" buffer.
-
-Here is one such case where "nfrontp"
-crossed boundaries of "netobuf", and
-pointing to another global variable.
-
-(gdb) p &netobuf[8255]
-$5 = 0x55c93afe8b1f <netobuf+8255> ""
-(gdb) p nfrontp
-$6 = 0x55c93afe8c20 <terminaltype> "\377"
-(gdb) p &terminaltype
-$7 = (char **) 0x55c93afe8c20 <terminaltype>
-(gdb)
-
-This resulted in crash of telnetd service
-with segmentation fault.
-
-Though this is DoS security bug, I couldn't
-find any CVE ID for this.
