CVE-2006-1343: Linux Kernel

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: version 2.4.0 only; version 2.6.0 only
