TITLE:
ZipTV ARJ Archive Handling and unacev2.dll Buffer Overflows

SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/20270/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
ZipTV Compression Components
http://secunia.com/product/11870/

DESCRIPTION:
Secunia Research has discovered two vulnerabilities in ZipTV, which
can be exploited by malicious people to compromise an application
using the library.

1) A boundary error within the TZipTV component when listing files in
ARJ archives can be exploited to cause a heap-based buffer overflow
via a specially-crafted ARJ archive with an overly large ARJ header
block.

Successful exploitation allows execution of arbitrary code when a
malicious ARJ archive is listed.

2) A boundary error in UNACEV2.DLL (ztvunacev2.dll) when extracting
ACE archives containing a file with an overly long filename can be
exploited to cause a stack-based buffer overflow.

Successful exploitation allows execution of arbitrary code when a
malicious ACE archive is extracted.

The vulnerabilities have been confirmed in the following versions.
* ZipTV for Delphi 7 version 2006.1.26.
* ZipTV for C++ Builder version 2006-1.16.

Other versions may also be affected.

SOLUTION:
Do not open untrusted archives.
