[原文]Multiple memory leaks in the LDAP component in Fedora Directory Server 1.0 allow remote attackers to cause a denial of service (memory consumption) via invalid BER packets that trigger an error, which might prevent memory from being freed if it was allocated during the ber_scanf call, as demonstrated using the ProtoVer LDAP test suite.


[CNNVD]Fedora Directory Server多个内存泄露漏洞(CNNVD-200602-189)

        Fedora Directory Server 1.0的LDAP组件中存在多处内存泄露。远程攻击者可以借助触发错误的无效BER数据包(如果其在ber_scanf调用过程中被分配,则可能阻止内存被释放)造成拒绝服务(内存占用率高),如使用ProtoVer LDAP测试套件演示的那样。

RedHat Fedora Directory Server 1.0

- 漏洞讨论

Fedora Directory Server is prone to multiple remote denial-of-service vulnerabilities. These issues may be triggered by malformed LDAP data.

These issues allow remote attackers to crash affected servers or to consume excessive CPU and memory resources. This will deny further service to legitimate users.

- 漏洞利用

These issues can be reproduced by utilizing the ProtoVer LDAP test suite.

- 解决方案

The vendor has released patches to address these issues. Please see the referenced Bugzilla bugs for further information.
