Description

This security bulletin contains information about 1 security vulnerability.


1) Information exposure (CVE-ID: CVE-2006-1343)

The vulnerability allows a local user to gain access to sensitive information.

net/ipv4/netfilter/ip_conntrack_core.c in Linux kernel 2.4 and 2.6, and possibly net/ipv4/netfilter/nf_conntrack_l3proto_ipv4.c in 2.6, does not clear sockaddr_in.sin_zero before returning IPv4 socket names from the getsockopt function with SO_ORIGINAL_DST, which allows local users to obtain portions of potentially sensitive memory.


Remediation

Install update from vendor's website.
