lha - several vulnerabilities

Two vulnerabilities were discovered in lha:

• CAN-2004-0234 - Multiple stack-based buffer overflows in the
  get_header function in header.c for LHA 1.14 allow remote attackers
  or local users to execute arbitrary code via long directory or file
  names in an LHA archive, which triggers the overflow when testing
  or extracting the archive.

• CAN-2004-0235 - Multiple directory traversal vulnerabilities in LHA
  1.14 allow remote attackers or local users to create arbitrary
  files via an LHA archive containing filenames with (1) … sequences
  or (2) absolute pathnames with double leading slashes
  (“//absolute/path”).

For the current stable distribution (woody), these problems have been
fixed in version 1.14i-2woody1.

For the unstable distribution (sid), these problems have been fixed in
version 1.14i-8.

We recommend that you update your lha package.
