Array index error in the maketable function in unlzh.c in the LZH decompression component in gzip 1.3.5, when running on certain platforms, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted GZIP archive that triggers an out-of-bounds write, aka a "stack modification vulnerability."

unlzh.c in the LHZ component in gzip 1.3.5 allows context-dependent attackers to cause a denial of service (infinite loop) via a crafted GZIP archive.

Buffer overflow in the maketable function in the LHZ component in gzip 1.3.5 allows context-dependent attackers to execute arbitrary code via a crafted decoding table in a GZIP archive.

Buffer underflow in the buildtree function in unpack.c in gzip 1.3.5 allows context-dependent attackers to execute arbitrary code via a crafted leaf count table that causes a write to a negative index.

Flaw bug created to hold information about an old flaw we knew something about. For more details see the MITRE CVE description.
