Description:
A vulnerability has been reported in OpenOffice, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a truncation error within the ""rtl_allocateMemory()" function. This can be exploited to cause an out-of-bounds array access by e.g. tricking a user into opening a malicious document.
Successful exploitation may allow the execution of arbitrary code on 64bit platforms.
Note: Reportedly, the pre-built packages distributed by OpenOffice.org and versions compiled with the system allocator ("--with-alloc=system" configuration option) are unaffected.
Solution:
Use the pre-built packages provided by OpenOffice.org.
Fixed in the CVS repository.
