Debian: sysstat Insecure temporary file vulnerability
Summary
Alan Cox discovered that the isag utility (which graphically displays
data collected by the sysstat tools), creates a temporary file without
taking proper precautions. This vulnerability could allow a local
attacker to overwrite files with the privileges of the user invoking
isag.
The update used in DSA 460-1 did not fix every occurrence of the bug.
DSA 460-2 includes a more complete fix.
For the current stable distribution (woody) this problem has been
fixed in version 4.0.4-1woody2.
For the unstable distribution (sid) this problem has been fixed in
version 5.0.2-1.
We recommend that you update your sysstat package.
