Summary
Red Hat Security Advisory: unzip security update

Notes

Topic
The unzip and tar utilities contain vulnerabilities which can allow arbitrary files to be overwritten during archive extraction. [updated Jan 22 2003] Added description of CAN-2002-1216 which was also fixed by these erratum packages.
Details
The unzip and tar utilities are used for dealing with archives, which are multiple files stored inside of a single file. A directory traversal vulnerability in unzip version 5.42 and earlier, as well as GNU tar 1.13.19 and earlier, allows attackers to overwrite arbitrary files during archive extraction via a ".." (dot dot) in an extracted filename (CAN-2001-1267, CAN-2001-1268). In addition, unzip version 5.42 and earlier version also allow attackers to overwrite arbitrary files during archive extraction via filenames in the archive that begin with the "/" (slash) character (CAN-2001-1269). During testing of the fix to GNU tar, we discovered that GNU tar 1.13.25 was still vulnerable to a modified version of the same problem. Red Hat has provided a patch to tar 1.3.25 to correct this problem (CAN-2002-0399). GNU tar 1.13.19 and other versions before 1.13.25 allow remote attackers to overwrite arbitrary files via a symlink attack, as the result of a modification that effectively disabled the security check. (CAN-2002-1216) Users of unzip and tar are advised to upgrade to these errata packages, containing unzip version 5.50 and a patched version of GNU tar 1.13.25, which are not vulnerable to these issues.
