      9 ------------------- original text ---------------------------
     10 The version of Gzip contained in this gate, 1.3.3, is the latest
     11 version released by the official maintainers. Following the release of
     12 this version, a number of issues were discovered which affected
     13 Solaris and for which it was deemed important to release a patch.
     14 However, the Gzip source code is no longer being maintained by the
     15 community. As a result, the diff file gzip-1.3.3.patch was created
     16 which contains the differences between our released version and the
     17 current official release. This is applied using gpatch during the
     18 build process.
     19 
     20 In order to distinguish the Sun patched version from the official
     21 community version, the version number as reported by the utility at
     22 runtime has been changed to: 1.3.3-patch.1
     23 
     24 If in the future a new official version of Gzip is released, it should
     25 be determined whether that later version still contains the problems
     26 fixed by this patch. If it does not, this patch can be removed from
     27 the gate and the build process when the later version is integrated
     28 into the gate. If they are still present, this patch will have to be
     29 modified to be applicable to that later version before it is
     30 integrated into the gate.

     32 The patch file contains the following changes:
     33 
     34 1) configure : The version number used during build time has been
     35    modifed as described above.
     36 
     37 2) gzip.c: [ 6283819 gzip TOCTOU file-permissions vulnerability ]
