Debian: man-db denial of service vulnerability
Summary
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.
