Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: unzip
Advisory ID: MDKSA-2003:073-1
Date: August 19th, 2003
Original Advisory Date: July 7th, 2003
Affected versions: 8.2, 9.0, 9.1, Corporate Server 2.1,
Multi Network Firewall 8.2
________________________________________________________________________
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.
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.
