Summary	(en) A vulnerability was determined in dnsmasq up to 2.73rc6. Affected by this issue is the function parse_dhcp_opt of the file src/option.c of the component Config File Handler. This manipulation of the argument m causes null pointer dereference. The attack can only be executed locally. The exploit has been publicly disclosed and may be utilized. The actual existence of this vulnerability is currently in question. This attack requires manipulating config files which might not be a realistic scenario in many cases. The vendor was contacted early about this disclosure but did not respond in any way.	(en) Rejected reason: ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: Based on the analysis by MITRE and review of community feedback, the reported conditions represent expected and intentional behavior within dnsmasq's documented design, rather than security vulnerabilities.
