Debian Security Advisory DSA 843-1 - Two vulnerabilities have been discovered in the ARC archive program under Unix. Eric Romang discovered that the ARC archive program under Unix creates a temporary file with insecure permissions which may lead to an attacker stealing sensitive information. Joey Schulze discovered that the temporary file was created in an insecure fashion as well, leaving it open to a classic symlink attack.

Debian-specific: no
CVE ID         : CAN-2005-2945 CAN-2005-2992

Two vulnerabilities have been discovered in the ARC archive program
under Unix.  The Common Vulnerabilities and Exposures project
identifies the following problems:

CAN-2005-2945

    Eric Romang discovered that the ARC archive program under Unix
    creates a temporary file with insecure permissions which may lead
    to an attacker stealing sensitive information.

CAN-2005-2992

    Joey Schulze discovered that the temporary file was created in an
    insecure fashion as well, leaving it open to a classic symlink
    attack.

The old stable distribution (woody) does not contain arc packages.

For the stable distribution (sarge) these problems have been fixed in
version 5.21l-1sarge1.

For the unstable distribution (sid) these problems have been fixed in
version 5.21m-1.

We recommend that you upgrade your arc package.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

ARC ARC 5.21 j

- 漏洞讨论

ARC creates temporary files in an insecure manner.

An attacker with local access could potentially exploit this issue to view files and obtain privileged information. The attacker may also perform symlink attacks, overwriting arbitrary files in the context of the affected application.

Exploitation would most likely result in loss of confidentiality and theft of privileged information. Successful exploitation of a symlink attack may result in sensitive configuration files being overwritten. This may result in a denial of service; other attacks may also be possible.

ARC 5.21j and earlier versions are reported to be vulnerable.

- 漏洞利用

There is no exploit required.

- 解决方案

Debian has released security advisory DSA 843-1 addressing this issue. Please see the referenced advisory for further information.

Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or are aware of more recent information, please mail us at: vuldb@securityfocus.com <mailto:vuldb@securityfocus.com>.
