Debian alert: New version of glibc released
-----BEGIN PGP SIGNED MESSAGE----- - ------------------------------------------------------------------------ Debian Security Advisory security@debian.org http://www.debian.org/security/ Wichert Akkerman September 2, 2000 - ------------------------------------------------------------------------ Package: glibc Vulnerability: local exploit Debian-specific: no Recently two problems have been found in the glibc suite, which could be used to trick setuid applications to run arbitrary code. The first problem is the way ld.so handles environment variables: in order to provide a safe environment for setuid applications it removes certain the environment variables that can influence application execution such as LD_PRELOAD and LD_LIBRARY_PATH. Unfortunately there was a bug that could cause ld.so to not remove them under some conditions. This would affect setuid applications if they execute another binary without dropping privileges or cleaning up the environment themselves. The second problem is the locale handling in glibc. glibc checks for characters like `/' in the LANG and LC_* environment variables to see if someone is trying to trick a program into reading arbitrary files. Unfortunately there were some logic errors in those checks which could be used to make a setuid application use arbitrary files for localization settings, which can be exploited to trick it into executing arbitrary code. These problems have been fixed in version 2.1.3-13, and we recommend that you upgrade your glibc package immediately. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. You may use an automated update by adding the resources from the footer to the proper configuration. Debian GNU/Linux 2.1 alias slink - ------------------------------------ No update is available for slink; we will release an advisory with more information about this release later. Debian GNU/Linux 2.2 alias potato - ------------------------------------ Potato was released for the alpha, arm, i386, m68k, powerpc and sparc architectures. At this moment packages for m68k are not yet available. As soon as they are ready we will put them online and list them on the security pages at http://security.debian.org/.
