Package        : freeradius
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE IDs        : CVE-2005-4744 CVE-2006-1354
BugTraq IDs    : 17171 17293
Debian Bug     : 359042

Several problems have been discovered in freeradius, a
high-performance and highly configurable RADIUS server.  The Common
Vulnerabilities and Exposures project identifies the following


    SuSE researchers have discovered several off-by-one errors may
    allow remote attackers to cause a denial of service and possibly
    execute arbitrary code.


    Due to insufficient input validation it is possible for a remote
    attacker to bypass authentication or cause a denial of service.

The old stable distribution (woody) does not contain this package.

For the stable distribution (sarge) this problem has been fixed in
version 1.0.2-4sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 1.1.0-1.2.

We recommend that you upgrade your freeradius package.
