Affects: Ports collection prior to the correction date.
Vendor status: Updated version released
FreeBSD only: NO
oops is a caching WWW proxy server.
II. Problem Description
The oops port, versions prior to 1.5.2, contains remote
vulnerabilities through buffer and stack overflows in the HTML parsing
code. These vulnerabilities may allow remote users to execute
arbitrary code as the user running oops.
The oops port is not installed by default, nor is it "part of FreeBSD"
as such: it is part of the FreeBSD ports collection, which contains over
4200 third-party applications in a ready-to-install format. The ports
collections shipped with FreeBSD 3.5.1 and 4.2 contain this problem
since it was discovered after the releases.
FreeBSD makes no claim about the security of these third-party
applications, although an effort is underway to provide a security
audit of the most security-critical ports.
Malicious remote users may execute arbitrary code as the user running
If you have not chosen to install the oops port/package, then your
system is not vulnerable to this problem.
Deinstall the oops port/package, if you have installed it.
One of the following:
1) Upgrade your entire ports collection and rebuild the oops port.
2) Deinstall the old package and install a new package dated after the
correction date, obtained from:
