Summary

ISC DHCP 4.1.2 through 4.2.4 and 4.1-ESV before 4.1-ESV-R6 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed client identifier.

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.

  • NASL familyMandriva Local Security Checks
    NASL idMANDRIVA_MDVSA-2012-115.NASL
    descriptionMultiple vulnerabilities has been discovered and corrected in ISC DHCP : An unexpected client identifier parameter can cause the ISC DHCP daemon to segmentation fault when running in DHCPv6 mode, resulting in a denial of service to further client requests. In order to exploit this condition, an attacker must be able to send requests to the DHCP server (CVE-2012-3570). An error in the handling of malformed client identifiers can cause a DHCP server running affected versions (see Impact) to enter a state where further client requests are not processed and the server process loops endlessly, consuming all available CPU cycles. Under normal circumstances this condition should not be triggered, but a non-conforming or malicious client could deliberately trigger it in a vulnerable server. In order to exploit this condition an attacker must be able to send requests to the DHCP server (CVE-2012-3571). Two memory leaks have been found and fixed in ISC DHCP. Both are reproducible when running in DHCPv6 mode (with the -6 command-line argument.) The first leak is confirmed to only affect servers operating in DHCPv6 mode, but based on initial code analysis the second may theoretically affect DHCPv4 servers (though this has not been demonstrated.) (CVE-2012-3954). The updated packages have been upgraded to the latest version (4.2.4-P1) which is not affected by these issues.

    titleSuSE 11.1 Security Update : dhcp (SAT Patch Number 6671)
  • NASL familyRed Hat Local Security Checks
    NASL idREDHAT-RHSA-2012-1140.NASL
    descriptionUpdated dhcp packages that fix one security issue are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address. A denial of service flaw was found in the way the dhcpd daemon handled zero-length client identifiers. A remote attacker could use this flaw to send a specially crafted request to dhcpd, possibly causing it to enter an infinite loop and consume an excessive amount of CPU time. (CVE-2012-3571) Upstream acknowledges Markus Hietava of the Codenomicon CROSS project as the original reporter of this issue. Users of DHCP should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, all DHCP servers will be restarted automatically.

    descriptionThis update provides dhcp 4.2.4-p1, which fixes the dhcpv6 server crashing while accessing the lease on heap and provides the following additional fixes : - Security fixes : - Previously the server code was relaxed to allow packets with zero length client ids to be processed. Under some situations use of zero length client ids can cause the server to go into an infinite loop. As such ids are not valid according to RFC 2132 section 9.14 the server no longer accepts them. Client ids with a length of 1 are also invalid but the server still accepts them in order to minimize disruption. The restriction will likely be tightened in the future to disallow ids with a length of 1. (ISC-Bugs #29851, CVE-2012-3571) - When attempting to convert a DUID from a client id option into a hardware address handle unexpected client ids properly. (ISC-Bugs #29852, CVE-2012-3570) - A pair of memory leaks were found and fixed. (ISC-Bugs #30024, (CVE-2012-3954) ) - Further upstream fixes : - Moved lease file check to a separate action so it is not used in restart -- it can fail when the daemon rewrites the lease causing a restart failure then. - Request dhcp6.sntp-servers in /etc/dhclient6.conf and forward to netconfig for processing. - Rotate the lease file when running in v6 mode. (ISC-Bugs #24887) - Fixed the code that checks if an address the server is planning to hand out is in a reserved range. This would appear as the server being out of addresses in pools with particular ranges. (ISC-Bugs #26498) - In the DDNS code handle error conditions more gracefully and add more logging code. The major change is to handle unexpected cancel events from the DNS client code. (ISC-Bugs #26287) - Tidy up the receive calls and eliminate the need for found_pkt. (ISC-Bugs #25066) - Add support for Infiniband over sockets to the server and relay code. - Modify the code that determines if an outstanding DDNS request should be cancelled. This patch results in cancelling the outstanding request less often. It fixes the problem caused by a client doing a release where the TXT and PTR records weren

    descriptionAn updated rhev-hypervisor5 package that fixes one security issue and various bugs is now available. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The rhev-hypervisor5 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. It was discovered that the formatted printing functionality in glibc did not properly restrict the use of alloca(). This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort. (CVE-2012-3406) This updated package provides updated components that include fixes for various security issues. These issues have no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers : CVE-2012-3817 (bind issue) CVE-2012-3571 (dhcp issue) CVE-2012-2313 (kernel issue) CVE-2012-0441 (nss issue) CVE-2012-2337 and CVE-2012-3440 (sudo issues) CVE-2012-2625 (xen issue) Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues.
