Summary

Multiple buffer overflows in Asterisk Open Source 1.4.x before 1.4.18.1 and 1.4.19-rc3, Open Source 1.6.x before 1.6.0-beta6, Business Edition C.x.x before C.1.6.1, AsteriskNOW 1.0.x before 1.0.2, Appliance Developer Kit before 1.4 revision 109386, and s800i 1.1.x before 1.1.0.2 allow remote attackers to (1) write a zero to an arbitrary memory location via a large RTP payload number, related to the ast_rtp_unset_m_type function in main/rtp.c; or (2) write certain integers to an arbitrary memory location via a large number of RTP payloads, related to the process_sdp function in channels/chan_sip.c.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

descriptionBUGTRAQ ID: 28308 CVE(CAN) ID: CVE-2008-1289 Asterisk是开放源码的软件PBX，支持各种VoIP协议和设备。 Asterisk在处理带有畸形数据的请求时存在漏洞，如果在INVITE消息的SDP负载中发送了无效的RTP负载类型号的话，就会导致写入无效的内存位置，允许攻击者控制某些部分的内存。 无效的内存写入发生在process_line()（channels/chan_sip.c文件5275行）所调用的 ast_rtp_unset_m_type()（main/rtp.c文件1655行）。ast_rtp_unset_mt_type()没有验证pt，而在ast_rtp_set_mt_type()（1642行）进行了验证。攻击者可以控制pt向很大的内存地址范围写入0。 如果在SIP INVITE消息的SDP负载发送了多于32个RTP负载类型数属性的话，就会覆盖栈缓冲区，允许攻击者控制写入的值。 在process_sdp()（channels/chan_sip.c文件4980行）中，rtpmap codecs存储到了32 int的数组found_rtpmap_codecs，映射中的codec数存储到了last_rtpmap_codec中。未经检查数组的大小便将 Codec附加到了数组（5258行），最多为64（SIP_MAX_LINES）。攻击者可以向缓冲区后的内存位置写入0到 256（MAX_RTP_PT）的值。 Asterisk Asterisk 1.6.x Asterisk Asterisk 1.4.x Asterisk Business Edition C.x.x Asterisk AsteriskNOW 1.0.x Asterisk Appliance Developer Kit SVN Asterisk s800i 1.1.x Asterisk -------- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： <a href=http://downloads.digium.com/pub/telephony/asterisk target=_blank>http://downloads.digium.com/pub/telephony/asterisk</a> <a href=http://www.asterisknow.org/ target=_blank>http://www.asterisknow.org/</a>
