Background - -icecast is a server for streaming MP3 audio. - -II. Problem Description - -The icecast software, versions prior to 1.3.7_1, contains multiple -format string vulnerabilities, which allow a remote attacker to -execute arbitrary code as the user running icecast, usually the root -user. - -There are a number of other potential abuses of format strings which -may or may not pose security risks, but have not currently been -audited. - -The icecast port is not installed by default, nor is it "part of -FreeBSD" as such: it is part of the FreeBSD ports collection, which -contains nearly 4700 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. - -III. Impact - -Arbitrary remote users can execute arbitrary code on the local system -as the user running icecast, usually the root user. - -If you have not chosen to install the icecast port/package, then your -system is not vulnerable to this problem. - -IV. Workaround - -Deinstall the icecast port/package, if you have installed it. - -V. Solution - -Consider running the icecast software as a non-privileged user to -minimize the impact of further security vulnerabilities in this -software. - -To upgrade icecast, choose one of the following options: - -1) Upgrade your entire ports collection and rebuild the icecast port. - -2) Deinstall the old package and install a new package dated after the -correction date, obtained from: - -[i386] -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/audio/icecast-1.3.7_1.tgz -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/audio/icecast-1.3.7_1.tgz - -NOTE: It may be several days before updated packages are available - -[alpha] -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/audio/icecast-1.3.7_1.tgz -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/audio/icecast-1.3.7_1.tgz - -3) download a new port skeleton for the icecast port from: - -http://www.freebsd.org/ports/ - -and use it to rebuild the port. - -4) Use the portcheckout utility to automate option (3) above.
