CVE-2014-0128
説明
CVE.org より
Squid 3.1 before 3.3.12 and 3.4 before 3.4.4, when SSL-Bump is enabled, allows remote attackers to cause a denial of service (assertion failure) via a crafted range request, related to state management.
詳細
This issue did not affect the versions of squid as shipped with Red Hat Enterprise Linux 5 as they did not include support for SSL-bump.
軽減策
To work-around this issue, disable SSL-bump for clients affected by adding "ssl_bump none" rule(s) at the top of the ssl_bump configuration directives. Alternatively, disable the SSL-bump feature completely by removing the "ssl-bump" option from all http_port and/or https_port configuration directives.

Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
