    glibc in unstable has a security hole.

    This is a late warning for all the users that run unstable but don’t scan bugtraq, debian-devel or any other major lists. glibc in unstable has a security hole that allows anyone to read almost any file. new glibc is in incoming (or was this morning) update your system ASAP.

    How about pointers to bugtraq, etc. regarding the bug, severity, etc. Is it a local or remote exploit?

    Link to bugtraq

    Anyway, this seems to be the problem:

    A problem in versions of glibc 2.1.9 and greater allow a local user access to restricted files. A typo in the glibc source creates a situation of insufficent validation and clearing of the environment variable RESOLV_HOST_CONF, a controlled environment variable that is normally cleared when suid/sgid programs are executed. Therefore, it is possible for a local user to set this environment variable to a sensitive system file and gain read privileges to the file. This vulnerability makes it possible for a user with malicious intent to read the shadow file, and gain access to encrypted passwords. Successful exploitation of this vulnerability could lead to compromise of system accounts, elevated privileges, and potentially administrative access.
