Package        : lha
Vulnerability  : several
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2004-0234 CAN-2004-0235

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.
