SECUNIA ADVISORY ID:
SA14660

VERIFY ADVISORY:
http://secunia.com/advisories/14660/

CRITICAL:
Less critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Proview Disassembler (PVDasm) 1.x
http://secunia.com/product/4827/

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

The vulnerability is caused due to a boundary error when handling the
names of opened files. This can be exploited to cause a stack-based
buffer overflow by tricking a user into opening a file with an overly
long (about 134 bytes) filename.

Successful exploitation may allow execution of arbitrary code.

The vulnerability has been confirmed in version 1.5f and has also
been reported in version 1.6b. Other versions may also be affected.

SOLUTION:
Don't disassemble files with overly long, specially crafted
filenames.

PROVIDED AND/OR DISCOVERED BY:
