Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple vulnerabilities in MIT Kerberos 5 could potentially result in
the execution of arbitrary code.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-crypt/mit-krb5 < 1.5.2 >=3D 1.5.2
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The Kerberos administration daemon, and possibly other applications
using the GSS-API or RPC libraries, could potentially call a function
pointer in a freed heap buffer, or attempt to free an uninitialized
pointer.
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker may be able to crash an affected application, or
potentially execute arbitrary code with root privileges.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All MIT Kerberos 5 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dapp-crypt/mit-krb5-1.5.2"
