DESCRIPTION:
Two vulnerabilities have been discovered in GnuCash, which can be
exploited by malicious people to compromise a user's system.

1) The application bundles a vulnerable version of the Pthreads-win32
library, which loads libraries (e.g. quserex.dll) in an insecure
manner and can be exploited to load arbitrary libraries.

For more information:
SA41215

2) The application loads an executable (perl.exe) in an insecure
manner, which can be exploited to execute an arbitrary program.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code, but requires tricking a user into e.g. opening
".gnucash" file located on a remote WebDAV or SMB share.

The vulnerabilities are confirmed in version 2.4.7 r20813 running on
Windows. Other versions may also be affected.

SOLUTION:
Do not open untrusted files.
