DESCRIPTION:
Secunia Research has discovered a vulnerability in 7-Zip, which can
be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error when handling an
ARJ block that is larger than 2600 bytes. This can be exploited to
cause a stack-based buffer overflow when a specially crafted ARJ file
is opened.
Successful exploitation allows arbitrary code execution.
The vulnerability has been confirmed in version 3.13, 4.23, and 4.26
BETA. Other versions may also be affected.
