UNKNOWN Summary
ntp_request.c in ntpd in NTP before 4.2.4p8, and 4.2.5, allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons.

description | This module exploits a denial of service vulnerability within the NTP (network time protocol) demon. By sending a single packet to a vulnerable ntpd server (Victim A), spoofed from the IP address of another vulnerable ntpd server (Victim B), both victims will enter an infinite response loop. Note, unless you control the spoofed source host or the real remote host(s), you will not be able to halt the DoS condition once begun! |

It was discovered that nfs-utils did not use tcp_wrappers correctly. Certain hosts access rules defined in '/etc/hosts.allow' and '/etc/hosts.deny' may not have been honored, possibly allowing remote attackers to bypass intended access restrictions. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2008-4552 to this issue. c. vMA and Service Console package glib2 updated to 2.12.3-4.el5_3.1 GLib is the low-level core library that forms the basis for projects such as GTK+ and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system. Multiple integer overflows in glib/gbase64.c in GLib before 2.20 allow context-dependent attackers to execute arbitrary code via a long string that is converted either from or to a base64 representation. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2008-4316 to this issue. d. vMA and Service Console update for openssl to 0.9.8e-12.el5 SSL is a toolkit implementing SSL v2/v3 and TLS protocols with full- strength cryptography world-wide. Multiple denial of service flaws were discovered in OpenSSL's DTLS implementation. A remote attacker could use these flaws to cause a DTLS server to use excessive amounts of memory, or crash on an invalid memory access or NULL pointer dereference. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386, CVE-2009-1387 to these issues. An input validation flaw was found in the handling of the BMPString and UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex() function. An attacker could use this flaw to create a specially crafted X.509 certificate that could cause applications using the affected function to crash when printing certificate contents. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-0590 to this issue. e. vMA and Service Console package bind updated to 9.3.6-4.P1.el5_4.1 It was discovered that BIND was incorrectly caching responses without performing proper DNSSEC validation, when those responses were received during the resolution of a recursive client query that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4022 to this issue. f. vMA and Service Console package expat updated to 1.95.8-8.3.el5_4.2. Two buffer over-read flaws were found in the way Expat handled malformed UTF-8 sequences when processing XML files. A specially- crafted XML file could cause applications using Expat to fail while parsing the file. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-3560 and CVE-2009-3720 to these issues. g. vMA and Service Console package openssh update to 4.3p2-36.el5_4.2 A Red Hat specific patch used in the openssh packages as shipped in Red Hat Enterprise Linux 5.4 (RHSA-2009:1287) loosened certain ownership requirements for directories used as arguments for the ChrootDirectory configuration options. A malicious user that also has or previously had non-chroot shell access to a system could possibly use this flaw to escalate their privileges and run commands as any system user. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2904 to this issue. h. vMA and Service Console package ntp updated to ntp-4.2.2p1-9.el5_4.1.i386.rpm A flaw was discovered in the way ntpd handled certain malformed NTP packets. ntpd logged information about all such packets and replied with an NTP packet that was treated as malformed when received by another ntpd.

description | BUGTRAQ ID: 37255 CVE ID: CVE-2009-3563 NTP(Network Time Protocol)是用于通过网络同步计算机时钟的协议。 ntpdc查询和控制工具使用NTP模式7(MODE_PRIVATE),ntpq使用NTP模式6(MODE_CONTROL),而例程NTP时间传输使用模式1到5。在从非restrict ... noquery或restrict ... ignore网段所列出的地址接收到错误的模式7请求或模式7错误响应时,ntpd会回复模式7出错响应并记录一条消息日志。如果攻击者能够在发送给主机 B的模式7响应报文中伪造ntpd主机A的源地址,则只要报文还可以通过主机A和B都会连续的向彼此发送出错响应;如果攻击者可以在发送给ntpd主机A 的模式7响应报文中伪造ntpd主机A的地址,主机A就会无限的响应其本身,耗尽CPU资源并生成过多日志。 University of Delaware NTP 4.2.x 临时解决方法: * 使用ntp.conf配置文件的restrict ... noquery或restrict ... ignore选项限制源地址。 * 过滤指定了源和目标端口123的NTP模式7报文。 厂商补丁: Debian ------ Debian已经为此发布了一个安全公告(DSA-1948-1)以及相应补丁: DSA-1948-1:New ntp packages fix denial of service 链接:http://www.debian.org/security/2009/dsa-1948 补丁下载: Source archives:
