F-Secure Corp. has patched several vulnerabilities in its security
products, the most critical of which could be used to run unauthorized
software on a victim's computer.
The most critical of these bugs affects F-Secure's antivirus products. A
flaw in the way the software unpacks files that have been compressed
using the LHA archiving format, could allow an attacker to crash the
system, or even run unauthorized software on the computer, F-Secure said
in an advisory, published Wednesday.
This flaw is related to a similar flaw in the Gzip decompression utility
that was discovered last September, F-Secure said.
Security vendor Secunia ApS rates the bug as highly critical. The flaw
affects F-Secure's Anti-Virus, Internet Gatekeeper and Internet Security

software was also patched Wednesday. This flaw could be used by an
attacker with access to the local system to get into unauthorized parts
of the system in what is called a privilege escalation attack.
Users of some versions of F-Secure Anti-Virus and Internet Security have
been automatically delivered the software patches for these flaws,
F-Secure said. A list of which products require hotfixes can be found

that could be used by attackers to launch a denial of service attack
against the security management software. Secunia rates this bug as
