Review: Absolute PC Security and Privacy - Miller never knew much about
viruses, or took them seriously, until a friend got infected and it turned
out to be more of a nuisance than he thought. So he decided to write a
book about them. And also about spam, since he was annoyed by that, too.

Review: Mastering Network Security, Second Edition - The introduction
states that this book is aimed at systems administrators who are not
security experts, but have some responsibility for ensuring the integrity
of their systems. That would seem to cover most sysadmins.

Description:
Al Viro found a buffer overflow in Window Maker 0.80.0 and earlier which

information to allocate a buffer. This could be exploited for example by
a user opening a malicious theme.

| Package: xpdf | ----------------------------//
| Date: 02-06-2003 |
+---------------------------------+
Description:
During an audit of CUPS, a printing system, Zen Parsec found an integer
overflow vulnerability in the pdftops filter. Since the code for pdftops
is taken from the Xpdf project, all versions of Xpdf including 2.01 are
also vulnerable to this issue. An attacker could create a PDF file that
could execute arbitrary code. This could would have the same access
privileges as the user who viewed the file with Xpdf.
