Fiedler Roman discovered that coreutils' parse_datetime() function has some flaws that may be exploitable if the date(1), touch(1), or potentially other programs, accept untrusted input for certain parameters. While researching this issue, he discovered that it was independently discovered by Bertrand Jacquin and reported at http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16872 $ touch '--date=TZ="123"345" @1' *** Error in `touch': free(): invalid pointer: 0x00007fffd33e55e0 *** Aborted $ date '--date=TZ="123"345" @1' date[394]: segfault at 7fff24000000 ip 00007f6dd5b73404 sp 00007fff27cce8f8 error 4 in libc-2.20.so[7f6dd5af7000+199000] Segmentation fault (From OE-Core rev: 54debe63cbd38dba56895541c434f895e158f70b) Signed-off-by: Maxin B.
