FreeRADIUS: Multiple Denial of Service vulnerabilities

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-dialup/freeradius	< 1.0.1	>= 1.0.1	All supported architectures

Related bugreports: #60587

Multiple Denial of Service vulnerabilities were found and fixed in FreeRADIUS.

2. Impact Information

FreeRADIUS is an open source RADIUS authentication server implementation.

There are undisclosed defects in the way FreeRADIUS handles incorrect received packets.

A remote attacker could send specially-crafted packets to the FreeRADIUS server to deny service to other users by crashing the server.

3. Resolution Information

There is no known workaround at this time.

All FreeRADIUS users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge sync

# emerge -pv ">=net-dialup/freeradius-1.0.1"
# emerge ">=net-dialup/freeradius-1.0.1"
