Vulnerability Assessment Details

MDKSA-2003:073-1: unzip

Vulnerability Assessment Summary
Check for the version of the unzip package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2003:073-1 (unzip).


A vulnerability was discovered in unzip 5.50 and earlier that permits 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.
Update:
Ben Laurie found that the original patch used to fix this issue missed a case
where the path component included a quoted slash. An updated patch was used to
build these packages.
