Topic: screen port contains local root compromise Category: ports Module: screen Announced: 2000-09-12 Affects: Ports collection prior to the correction date. Corrected: 2000-09-01 Credits: Jouko Pynnönen Vendor status: Updated version released FreeBSD only: NO I. Background screen is a popular application that multiplexes a physical terminal between several processes. II. Problem Description The screen port, versions 3.9.5 and before, contains a vulnerability which allows local users to gain root privileges. This is accomplished by inserting string-formatting operators into configuration parameters, which may allow arbitrary code to be executed. The screen 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 3800 third-party applications in a ready-to-install format. The ports collections shipped with FreeBSD 3.5.1 and 4.1 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 Local users can obtain root privileges. If you have not chosen to install the screen port/package, then your system is not vulnerable to this problem. IV. Workaround Remove the setuid bit on the program: execute the following command as root: chmod 555 /usr/local/bin/screen-3.9.5 Note that this should be considered a temporary measure and may affect the behaviour of the screen program. V. Solution One of the following: 1) Upgrade your entire ports collection and rebuild the screen port. 2) Deinstall the old package and install a new package dated after the correction date, obtained from: ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/misc/screen-3.9.8.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/misc/screen-3.9.8.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/misc/screen-3.9.8.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/misc/screen-3.9.8.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/misc/screen-3.9.8.tgz NOTE: It may be several days before updated packages are available. 3) download a new port skeleton for the screen port from: http://www.freebsd.org/ports/ and use it to rebuild the port. 4) Use the portcheckout utility to automate option (3) above.

Topic: pine4 port allows denial of service Category: ports Module: pine4 Announced: 2000-09-13 Affects: Ports collection. Corrected: 2000-07-17 Credits: Juhapekka Tolvanen Vendor status: Contacted FreeBSD only: NO I. Background Pine is a popular mail user agent. II. Problem Description The pine4 port, versions 4.21 and before, contained a bug which would cause the program to crash when processing a folder which contains an email message with a malformed X-Keywords header. The message itself could be deleted within pine if identified, but other operations such as closing the folder with the message still present would cause the program to crash with no apparent cause, discarding changes to the mailbox. The FreeBSD port of pine4 was changed on 2000-07-17 to use an updated version of the c-client library which is used to handle the mailbox processing. This library does not contain the bug and versions of pine4 built with it (i.e. ports or packages dated after the correction date) do not suffer from this vulnerability. The pine4 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 3800 third-party applications in a ready-to-install format. The ports collections shipped with FreeBSD 4.1 and 3.5.1 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 Remote users can cause pine4 to crash when closing a mail folder by sending a malformed email. If you have not chosen to install the pine4 port/package, then your system is not vulnerable to this problem. IV. Workaround Deinstall the pine4 port/package, if you have installed it. It may be possible to use a mail filtering utility such as procmail (available in FreeBSD ports as /usr/ports/mail/procmail) to filter out the malformed X-Keywords header from incoming mail, but this solution is not discussed here. V. Solution One of the following: 1) Upgrade your entire ports collection and rebuild the pine4 port. 2) Deinstall the old package and install a new package dated after the correction date, obtained from: ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/mail/pine-4.21.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/mail/pine-4.21.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/mail/pine-4.21.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/mail/pine-4.21.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/mail/pine-4.21.tgz NOTE: Be sure to check the file creation date on the package, because the version number of the software has not changed. 3) download a new port skeleton for the listmanager port from: http://www.freebsd.org/ports/ and use it to rebuild the port. 4) Use the portcheckout utility to automate option (3) above.

Corrected: 2000-08-27 Vendor status: Updated version released FreeBSD only: NO I. Background Xchat is a popular graphical IRC client. II. Problem Description The xchat IRC client provides the ability to launch URLs displayed in an IRC window in a web browser by right clicking on the URL. However this was handled incorrectly in versions prior to 1.4.3, and prior to 1.5.7 in the 1.5 development series, and allowed a malicious IRC user to embed command strings in a URL which could cause an arbitrary command to be executed as the local user if the URL were to be "launched" in a browser as described above. The xchat 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 3800 third-party applications in a ready-to-install format. The ports collections shipped with FreeBSD 4.0 and 3.5.1 contain this problem since it was discovered after the release. 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 Remote IRC users can cause an arbitrary command to be executed by the local user, if they attempt to launch a malformed URL by right clicking on it. If you have not chosen to install the xchat or xchat-devel ports/packages, then your system is not vulnerable to this problem. IV. Workaround Do not attempt to launch URLs which contain the ` (backtick) character. V.
