Debian 3.0 DSA 636-1 Moderate: Glibc Insecure Temporary Files Advisory

Several insecure uses of temporary files have been discovered in support scripts in the libc6 package which provices the c library for a GNU/Linux system. Trustix developers found that the catchsegv script uses temporary files insecurely. Openwall developers discovered insecure temporary files in the glibcbug script. These scripts are vulnerable to a symlink attack.. - --------------------------------------------------------------------------Debian Security Advisory DSA 636-1 This email address is being protected from spambots.
