MySQL users urged to upgrade to fix flaw
Users of MySQL, a popular open-source multithreaded, multiuser SQL database server, are being urged to upgrade to the latest version (4.0.20-r1) to correct a flaw that could allow an attacker to overwrite important data or corrupt and destroy system files, possibly leading to a denial of service. According to a Gentoo Linux advisory, "the MySQL database hot copy utility (, when using the scp method, uses temporary files with predictable names. A malicious local user with write-access to the /tmp directory could create a symbolic link pointing to a file, which may then be overwritten. In cases where mysqlhotcopy is run as root, a malicious user could create a symlink to a critical file such as /etc/passwd and cause it to be overwritten." There is no known workaround; all MySQL users should upgrade to the latest version.

While resources are being used to improve the speed and quality of data exchanges, more emphasis is needed to reduce spam and security problems that now plague the Net, according to the Associated Press.

Authorities are trying to crack down on the mechanisms by which spam, and phishing in particular, is spawned.

XP SP2 bigger headache for smaller companies
While new research suggests 1 in 10 computers will have compatibility issues with the XP SP2 update, the problem will be worse for companies with less than 100 installations. Canada-based AssetMetrix, which provides IT infrastructure management, said smaller businesses have a 12% incompatibility rate, while only 6% of larger companies face the same deployment dilemma. An AssetMetrix executive told NewsFactor smaller companies have a wider variety of applications and lesser-known programs that aren't compatible with new features in the service pack. Microsoft's identified 60 applications that must be modified to work with SP2.
