INFORMATION BULLETIN
Linux worm Adore
April 4, 2001 22:00 GMT Number L-067
______________________________________________________________________________
PROBLEM: A new worm variant, Adore, of the Linux worms Ramen & Lion has
been discovered by SANS. This is the continued evolution of the
Ramen & Lion worm capabilities
PLATFORM: Linux x86 systems which are not patched with the latest releases
of/patches for LPRng, rpc-statd, wu-ftpd, and BIND.
DAMAGE: The new worm scans systems for exploitable holes in LPRng,
rpc-statd, wu-ftpd and BIND. This exploit gains root access and
installs a backdoor on a system. The worm also mails system
information to specific e-mail addresses and compromises some
system files.
SOLUTION: All systems should be patched to the latest releases/patches.
If a system has been infected, use the SANS utility named
'adorefind' to search an infected system for Adore installed
files. Keep in mind that as the worm mutates in the future,
the utility may not find all changed files/directories.
______________________________________________________________________________
VULNERABILITY The risk is HIGH. These vulnerabilities targeted by Adore are
ASSESSMENT: being actively exploited. However, CIAC has received one report
of the worm itself.
