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.
