Categoría:	Huawei EulerOS Local Security Checks
Título:	Huawei EulerOS: Security Advisory for dnsmasq (EulerOS-SA-2017-1239)
Resumen:	The remote host is missing an update for the Huawei EulerOS 'dnsmasq' package(s) announced via the EulerOS-SA-2017-1239 advisory.
Descripción:	Summary: The remote host is missing an update for the Huawei EulerOS 'dnsmasq' package(s) announced via the EulerOS-SA-2017-1239 advisory. Vulnerability Insight: A heap buffer overflow was found in dnsmasq in the code responsible for building DNS replies. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. (CVE-2017-14491) A heap buffer overflow was discovered in dnsmasq in the IPv6 router advertisement (RA) handling code. An attacker on the local network segment could send crafted RAs to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. This issue only affected configurations using one of these options: enable-ra, ra-only, slaac, ra-names, ra-advrouter, or ra-stateless. (CVE-2017-14492) A stack buffer overflow was found in dnsmasq in the DHCPv6 code. An attacker on the local network could send a crafted DHCPv6 request to dnsmasq which would cause it to a crash or, potentially, execute arbitrary code. (CVE-2017-14493) An information leak was found in dnsmasq in the DHCPv6 relay code. An attacker on the local network could send crafted DHCPv6 packets to dnsmasq causing it to forward the contents of process memory, potentially leaking sensitive data. (CVE-2017-14494) Affected Software/OS: 'dnsmasq' package(s) on Huawei EulerOS V2.0SP1. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
