| Problem Description |
NULL Dereference (CVE-2006-4334)
A stack modification vulnerability (where a stack buffer can be
modified out of bounds, but not in the traditional stack overrun sense)
exists in the LZH decompression support of gzip. (CVE-2006-4335)
A .bss buffer underflow exists in gzip's pack support, where a loop
from build_tree() does not enforce any lower bound while constructing
the prefix table. (CVE-2006-4336)
A .bss buffer overflow vulnerability exists in gzip's LZH support, due
to it's inability to handle exceptional input in the make_table()
function, a pathological decoding table can be constructed in such a
way as to generate counts so high that the rapid growth of `nextcode`
exceeds the size of the table[] buffer. (CVE-2006-4337)
A possible infinite loop exists in code from unlzh.c for traversing the
branches of a tree structure. This makes it possible to disrupt the
operation of automated systems relying on gzip for data decompression,
resulting in a minor DoS. (CVE-2006-4338) Updated packages have been
patched to address these issues.
