CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Adjacent	AV	The vulnerable system is bound to a protocol stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared proximity (e.g., Bluetooth, NFC, or IEEE 802.11) or logical network (e.g., local IP subnet), or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN within an administrative network zone). One example of an Adjacent attack would be an ARP (IPv4) or neighbor discovery flood leading to a denial of service on the local LAN segment (e.g., CVE-2013-6014).
Privileges Required	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Scope	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	High	C	There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity	High	I	There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

The vulnerability is caused due to multiple boundary errors when reading the filename of a compressed file from ALZ, ARJ, ZIP, UUE or XXE archives. This can be exploited to cause a stack-based buffer overflow (ALZ), or a heap-based buffer overflow (ARJ / ZIP / UUE / XXE). Successful exploitation allows execution of arbitrary code when a malicious ALZ / ARJ archive is opened, or when a ZIP / UUE / XXE archive is extracted. ====================================================================== 4) Solution Update to version 6.13 (Korean and International) ====================================================================== 5) Time Table 19/09/2005 - Initial vendor notification. 20/09/2005 - Initial vendor reply. 28/09/2005 - Notified by vendor that fixed version has been released. 05/10/2005 - Public disclosure. ====================================================================== 6) Credits Discovered by Tan Chew Keong, Secunia Research. ====================================================================== 7) References No references available. ====================================================================== 8) About Secunia Secunia collects, validates, assesses, and writes advisories regarding all the latest software vulnerabilities disclosed to the public.
