could use this to potentially run malicious code on the affected
machine. For more, go to:

**********
Mandriva patches squid
According to an alert from Mandriva, "A bug was found in the way
that Squid handles DNS replies. If the port Squid uses for DNS
requests is not protected by a firewall, it is possible for a
remote attacker to spoof DNS replies, possibly redirecting a
user to spoofed or malicious content." For more, go to:
<http://www.mandriva.com/security/advisories?name=MDKSA-2005:104>
Mandriva fixes dbus
A flaw in the way dbus messages are sent between applications
could be exploited by another user to view the data being sent.

Today's roundup of virus alerts:
W32/Rbot-AGH - An Rbot variant that exploits the Windows LSASS
and RPC-DCOM vulnerabilities as it spreads through network
shares. It installs "LimeWire.exe" on the infected machine and
allows backdoor access through IRC. (Sophos)
W32/Sdbot-ZM - This Sdbot variant exploits a number of known
Windows flaws in its attempt to infect a machine. If successful,
it drops "nawdll32.exe" in the Windows System directory and it
can allow backdoor access via IRC. (Sophos)
Troj/Drivol-A - A Trojan that attempts to download and run
malicious code from a remote Web site. It initially installs
"fvek.exe" on the infected machine. (Sophos)
W32/Mytob-BV - Wow, another Mytob variant. Again, it spreads
through e-mail and network shares, providing backdoor access to
the infected machine through IRC. This particular variant drops
"TimeManager.exe" on the infected machine. (Sophos)
Troj/Pyfls-A - Another Trojan that tries to download additional
malicious code from a preconfigured site. It drops "b.tmp" on
the infected host. (Sophos)
W32.Codbot.AL - A new bot that can be used to log keystrokes and
download malware. It spreads by exploiting some well-known
Windows vulnerabilities and provides unauthorized access through
IRC. (Panda Software)
W32.Semapi.A - An e-mail worm that uses variable message
attributes when it spreads. Fortunately, it does display the
message "semapi.dll" cannot be found. (Panda Software)
