ArcPad ".apm" Map File Handling Buffer Overflow

SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/18294/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
ArcPad 7.x
http://secunia.com/product/6739/

DESCRIPTION:
bratax has discovered a vulnerability in ArcPad, which potentially
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when processing a
".apm" map file. This can be exploited to cause a stack-based buffer
overflow via an overly long value in the "string" attribute of the
COORDSYS tag.

Successful exploitation may allow arbitrary code execution but
requires that the user is e.g. tricked into opening a specially
crafted ".apm" file.

The vulnerability has been confirmed in version 7.0.0.156 for
Windows. Other versions may also be affected.

SOLUTION:
Do not open ".apm" files from non-trusted sources.

PROVIDED AND/OR DISCOVERED BY:
