+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.
