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. ________________________________________________________________________
