    Package : man-db

    A previous man-db update (DSA-364-1) fixed buffer overruns in ult_src, a
    part of the "mandb" command that finds the canonical source file for
    each man page. However, this update introduced an error in the routine
    that resolves hardlinks: depending on the filenames of hardlinked man
    pages, that routine might itself overrun allocated memory, causing a
    segmentation fault.

    For the current stable distribution (woody), this problem has been fixed
    in version 2.3.20-18.woody.4.

    For the unstable distribution (sid), this problem has been fixed in
    version 2.4.1-13.

    We recommend that you update your man-db package.
