Linux kernel SCTP sctp_make_abort_user privilege escalation

kernel-sctp-privilege-escalation (28530) The risk level is classified as HighHigh Risk

Description:

Linux kernel could allow a local attacker to gain elevated privileges caused by an error in the sctp_make_abort_user function of the SCTP module. A local attacker could exploit this vulnerability to gain root privileges on the system.

Remedy:

Upgrade to the latest stable version of Linux kernel (2.6.17.10 or later), available from The Linux Kernel Archives. See References.

For Red Hat Linux:
Refer to RHSA-2006:0617-15 for patch, upgrade, or suggested workaround information. See References.

For Debian GNU/Linux:
Refer to DSA-1183-1 or DSA-1184-1 for patch, upgrade, or suggested workaround information. See References.

For SUSE Linux:
Refer to SUSE-SA:2006:057 for patch, upgrade, or suggested workaround information. See References.

For other distributions:
Contact your vendor for upgrade or patch information.

Consequences:

Gain Privileges
