CVE-2006-1343: n/a vulnerability

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.

Security readout for executives and security teams

This is an old Linux kernel information leak. A local user could ask the kernel for an IPv4 socket destination and receive uninitialized bytes from kernel memory. The issue matters most where legacy Linux 2.4 or 2.6 systems still run with local user access. Exposure is most likely on legacy Linux 2.4 or 2.6 kernels and products based on them. The source bundle includes Red Hat, Ubuntu, Debian, Mandriva, Trustix, and VMware ESX references, but does not provide a complete affected-version matrix. Treat this as a legacy hygiene issue unless exposed systems still exist. It is not presented as remotely exploitable or actively exploited, but it can leak kernel memory to local users and should be closed during legacy risk reduction. Mitigation focus: Apply the relevant vendor kernel security update for the affected distribution or appliance.; Retire or isolate unsupported Linux 2.4 and 2.6 systems.; Check vendor advisories for exact fixed kernel package versions..
