gzip

gzip (GNU zip) is a compression utility designed to be a replacement for 'compress'. Its main advantages over compress are much better compression and freedom from patented algorithms. The GNU Project uses it as the standard compression program for its system.

Release Notes: The "--keep" (-k) option was added to not delete input files, in line with other tools such as xz, lzip, and bzip2. A decompression issue with certain invalid data in the 'pack' format was fixed. An incorrect overwrite when compiled with optimization was fixed. zgrep's handling of multi-digit context options was fixed. zmore now acts more like 'more'.

Release Notes: CRC16 header checksums according to RFC 1952 are now checked and decoded. A case of accidental interactive input file removal was eliminated. Decompression of mixed compressed and uncompressed streams now works. Double-compression is avoided better. Various other changes were made.

Release Notes: Many changes were made since the last announcement. Most notably, a security vulnerability potentially allowing arbitrary code execution, reported as CVE-2010-0001, was fixed. Many other minor bugs were fixed.

What are you talking about. What version. You can see the version by typing gzip --version.

gzip buffer overflow revision
I laud the speed with which the buffer overflow problem was addressed, but the revision.h file has not been altered to reflect this change. While this is an administrative-only event, it makes it impossible to identify which version of gzip is in use.

It really needs fixed, guys.
