Security Bulletin: Vulnerabilities in the Network Security Services (NSS) affect the IBM FlashSystem models 840 and 900 (CVE-2015-7181, CVE-2015-7182, CVE-2015-7183)

Summary

There are vulnerabilities in Network Security Services (NSS) to which the IBM® FlashSystem™ 840 and IBM FlashSystem 900 are susceptible. An exploit of these vulnerabilities could allow a remote attacker to execute arbitrary code on a vulnerable system, cause the application to crash, or cause a denial of service.

Vulnerability Details

CVEID: CVE-2015-7181 DESCRIPTION: Mozilla Firefox could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-poison in the sec_asn1d_parse_leaf() function. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability using unknown attack vectors to execute arbitrary code on the vulnerable system or cause a denial of service.
