The sysstat package contains a set of utilities which enable system monitoring of disks, network, and other I/O activity.
It was found that the sysstat initscript created a temporary file in an insecure way. A local attacker could use this flaw to create arbitrary files via a symbolic link attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-3852 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow
networking and security best practices by implementing
firewalls, ACLs, physical security or other appropriate
access restrictions. Though Avaya believes such
restrictions should always be in place, risk to Avaya
products and the surrounding network from this potential
vulnerability may be mitigated by ensuring these
practices are implemented until such time as an Avaya provided
product update or the recommended Avaya action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period, but customers should not modify the System Product
operating system or application unless the change is approved by Avaya.
Making changes that are not approved may void the Avaya product service contract.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
| Vulnerability | Mitigating Factors |
|---|---|
|
CVE-2007-3852 |
Rated a Low as no critical system applications would be affected. |
