MDKSA-2003:073-1: unzip Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the unzip package
Detailed Explanation for this Vulnerability Test
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 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.
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.
