网络安全服务(NSS)是一组函数库,可跨平台提供SSL、S/MIME和其他Internet安全标准支持。

Sun Java Enterprise System和Java System目录服务器中所使用的NSS中存在内存泄露漏洞,如果远程攻击者执行了大量RSA加密操作的话,就会耗尽大量系统内存,导致拒绝服务。

Sun Java System Directory Server Enterprise Edition
Sun Java System Directory Server 5.2
Mozilla NSS 3.11
临时解决方法:

  • 使用以下命令重启LDAP服务进程:

在UNIX系统上(通常以root用户):

# <server instance path>/start-slapd

在Windows系统上,打开“服务”面板然后手动启动服务。

厂商补丁:

Sun

Sun已经为此发布了安全公告(Sun-Alert-102896,Sun-Alert-102670,Sun-Alert-102461)以及相应补丁:
