With this option, gzip no longer removes + named input files when compressing or decompressing. + +** Bug fixes + + gzip -d no longer malfunctions with certain invalid data in 'pack' format. + [bug introduced in gzip-0.8] + + When overwriting, gzip no longer acts as if you typed "y" when you type "n", + on some platforms when compiled with optimization. + [bug introduced in gzip-1.3.6] + + zgrep no longer malfunctions with a multi-digit context option like -15. + Now, it passes that option to grep (equivalent to -C15) just as it does + for single-digit options. [bug introduced in gzip-1.3.12] + + zmore now acts more like 'more', and is more portable to POSIXish hosts. + + +* Noteworthy changes in release 1.5 (2012-06-17) [stable] + +** Bug fixes + + gzip -d now decodes and checks header CRC16 checksums as specified by + the FHCRC section of Internet RFC 1952. + + "gzip -d -S '' precious.gz" is now rejected immediately. Before, + that command would emulate "rm -i precious.gz", but with an easily- + misunderstood prompt. I.e., gzip would ask if it's ok to remove the + existing file, "precious.gz". If you made the mistake of saying "yes", + it would remove that input file before attempting to uncompress it. + + gzip -cdf now properly handles input consisting of gzip'd data followed + by uncompressed data. Before it would output raw compressed input, too. + For example, now "(printf x|gzip; echo y)|gzip -dcf" prints "xy\n", + while before it would print "xy\n". + + gzip -rf no longer compresses files more than once (e.g., replacing + FOO with FOO.gz.gz) on file systems such as ZFS where a readdir + loop that unlinks and creates files can revisit output files. + + +* 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)".
