A user providing an invalid JID when creating a new bookmark (like 'foo') would reproducibly crash/segfault profanity, as it insists on checking string length behind the @ of the JID. However, it could be NULL if the user accidentally omitted it. The patch avoids the crash by NULL-checking and prevents getting there in the first place by checking the argument to "add". Backtrace of unpatched profanity with above command: Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000000 0x00007fff85699732 in strlen () (gdb) bt #0 0x00007fff85699732 in strlen () #1 0x00000001000965d2 in xmpp_strdup () #2 0x0000000100095d6d in xmpp_stanza_set_attribute () #3 0x0000000100011c5c in _send_bookmarks () #4 0x00000001000115a8 in _bookmark_add () #5 0x000000010003320d in cmd_bookmark () #6 0x000000010002a0f2 in cmd_execute () #7 0x0000000100003a1d in process_input () #8 0x00000001000037c7 in prof_run () #9 0x0000000100045032 in main () (gdb) |
