[原文]libpcp in Performance Co-Pilot (PCP) before 3.6.5 allows remote attackers to cause a denial of service and possibly execute arbitrary code via (1) a PDU with the numcreds field value greater than the number of actual elements to the __pmDecodeCreds function in p_creds.c; (2) the string byte number value to the __pmDecodeNameList function in p_pmns.c; (3) the numids value to the __pmDecodeIDList function in p_pmns.c; (4) unspecified vectors to the __pmDecodeProfile function in p_profile.c; the (5) status number value or (6) string number value to the __pmDecodeNameList function in p_pmns.c; (7) certain input to the __pmDecodeResult function in p_result.c; (8) the name length field (namelen) to the DecodeNameReq function in p_pmns.c; (9) a crafted PDU_FETCH request to the __pmDecodeFetch function in p_fetch.c; (10) the namelen field in the __pmDecodeInstanceReq function in p_instance.c; (11) the buflen field to the __pmDecodeText function in p_text.c; (12) PDU_INSTANCE packets to the __pmDecodeInstance in p_instance.c; or the (13) c_numpmid or (14) v_numval fields to the __pmDecodeLogControl function in p_lcontrol.c, which triggers integer overflows, heap-based buffer overflows, and/or buffer over-reads.


[CNNVD]Performance Co-Pilot 数字错误漏洞(CNNVD-201208-298)

        Performance Co-Pilot (PCP)是由SGI开发的一套支持系统级性能监视的服务,其中的 一个应用程序叫做"pmpost",默认安装时所有者为root,且设置了setuid位。
        Performance Co-Pilot 3.6.5之前版本中存在安全漏洞,恶意用户可利用导致DoS(拒绝服务),进而操控受影响系统。该漏洞源于libpcp协议解码功能内存在一些整数溢出错误。攻击者可利用该漏洞导致缓冲区溢出。

It was discovered that Performance Co-Pilot (pcp), a framework for
performance monitoring, contains several vulnerabilites.

CVE-2012-3418
	Multiple buffer overflows in the PCP protocol decoders can
	cause PCP clients and servers to crash or, potentially,
	execute arbitrary code while processing crafted PDUs.

CVE-2012-3419
	The "linux" PMDA used by the pmcd daemon discloses sensitive
	information from the /proc file system to unauthenticated
	clients.

CVE-2012-3420
	Multiple memory leaks processing crafted requests can cause
	pmcd to consume large amounts of memory and eventually crash.

CVE-2012-3421
	Incorrect event-driven programming allows malicious clients to
	prevent other clients from accessing the pmcd daemon.

To address the information disclosure vulnerability, CVE-2012-3419, a
new "proc" PMDA was introduced, which is disabled by default.  If you
need access to this information, you need to enable the "proc" PMDA.

For the stable distribution (squeeze), this problem has been fixed in
version 3.3.3-squeeze2.

For the unstable distribution (sid), this problem has been fixed in
version 3.6.5.

We recommend that you upgrade your pcp packages.

- 漏洞描述

Performance Co-Pilot is prone to multiple overflow conditions. The libpcp protocol fails to properly sanitize user-supplied input resulting in multiple heap-based buffer and integer overflows. This may allow a remote attacker to execute arbitrary code or cause a denial of service.

- 漏洞讨论

Performance Co-Pilot is prone to an information-disclosure vulnerability, multiple denial-of-service vulnerabilities, and multiple integer and heap-based buffer-overflow vulnerabilities.

Successful exploits can allow attackers to obtain sensitive information, execute arbitrary code in the context of the application, or cause denial-of-service conditions.

Performance Co-Pilot versions prior to 3.6.5 are vulnerable.

- 漏洞利用
