Mandrake Linux Advisory: unzip

Mandrake Linux Security Update Advisory

Problem Description:

A vulnerability was discovered in unzip 5.50 and earlier that
allows attackers to overwrite arbitrary files during archive
extraction by placing non-printable characters between two “.”
characters. These invalid characters are filtered which results in
a “..” sequence.

The patch applied to these packages prevents unzip from writing
to parent directories unless the “-:” command line option is
used.
