Description acount closed by user 2010-02-18 10:35:23 EST
* Noteworthy changes in release 1.4 (2010-01-20) [stable]

** Bug fixes

  gzip -d could segfault and/or clobber the stack, possibly leading to
  arbitrary code execution.  This affects x86_64 but not 32-bit systems.
  This fixes CVE-2010-0001.
  For more details, see http://bugzilla.redhat.com/554418

  gzip -d would fail with a CRC error for some valid inputs.
  So far, the only valid input known to exhibit this failure was
  compressed "from FAT filesystem (MS-DOS, OS/2, NT)".  In addition,
  to trigger the failure, your memcpy implementation must copy in
  the "reverse" order.
Comment 1 Karel Klíč 2010-02-18 10:51:24 EST
Thanks for the info. I'll update it.

We already patched gzip to fix CVE-2010-0001 in all Fedora releases, so the current version is not vulnerable.
