Red Hat Bugzilla – Bug 206579
restorecon segfaults when passed non-existent file
Last modified: 2014-03-16 23:02:23 EDT
Description of problem: # restorecon /sgdsfsuwyrqrw Segmentation fault Version-Release number of selected component (if applicable): policycoreutils-1.30.29-1
Fixed in policycoreutils-1.30.29-2 I have no idea what caused it but a rebuild of the package seems to have cleared it up.

Looking at the backtrace: (gdb) run /etc/blkid.tab Starting program: /sbin/restorecon /etc/blkid.tab Program received signal SIGSEGV, Segmentation fault. 0xb7efb7ab in __fprintf_chk () from /lib/libc.so.6 (gdb) where #0 0xb7efb7ab in __fprintf_chk () from /lib/libc.so.6 #1 0x080490c4 in restore (filename=<value optimized out>) at restorecon.c:168 #2 0x080495ae in process (buf=0xbfdb27b4 "/etc/blkid.tab") at restorecon.c:347 #3 0x080499fa in main (argc=2, argv=Cannot access memory at address 0xffffffbc ) at restorecon.c:442 #4 0xb7e30f2c in __libc_start_main () from /lib/libc.so.6 #5 0x08048c51 in _start () That "value optimized out" is suspicious - quite possibly dependent on the exact compiler release and flags. Was the -2 package built against the same compiler as -1? (I see a gcc update landed in rawhide in the last 48 hours or so....)
