Vulnerability Insight:
The following package is affected: gzip
CVE-2006-4334
Unspecified vulnerability in gzip 1.3.5 allows context-dependent
attackers to cause a denial of service (crash) via a crafted GZIP (gz)
archive, which results in a NULL dereference.
CVE-2006-4335
Array index error in the make_table 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.'
CVE-2006-4336
Buffer underflow in the build_tree 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.
CVE-2006-4337
Buffer overflow in the make_table 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.
CVE-2006-4338
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.
Solution:
