The Gzip package contains programs for compressing and decompressing files.
The following patch fixes two security vulnerabilities in Gzip: a path traversal bug when using the -N option (CAN-2005-1228), and a race condition in the file permission restore code (CAN-2005-0998):
patch -Np1 -i ../gzip-1.3.5-security_fixes-1.patch
The gzexe command calls tail with options that do not conform to newer versions of the POSIX standard, and therefore are not accepted by current versions of Coreutils. Fix this problem by issuing the following command:
sed -i 's/tail +/tail -n +/' gzexe.in
Prepare Gzip for compilation:
./configure --prefix=/usr
The gzexe script has the location of the gzip binary hard-wired into it. Because the location of the binary is changed later, the following command ensures that the new location gets placed into the script:
sed -i 's@"BINDIR"@/bin@g' gzexe.in
Compile the package:
make
This package does not come with a test suite.
Install the package:
make install
Move the gzip program to the /bin directory and create some commonly used symlinks to it:
mv -v /usr/bin/gzip /bin
rm -v /usr/bin/{gunzip,zcat}
ln -sv gzip /bin/gunzip
ln -sv gzip /bin/zcat
ln -sv gzip /bin/compress
ln -sv gunzip /bin/uncompress
