Summary

IBM DB2 for Linux, UNIX and Windows 9.2, 10.1, 10.5, and 11.1 (includes DB2 Connect Server) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking which could allow a local attacker to execute arbitrary code. IBM X-Force ID: 125159.

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.

    descriptionAccording to its version, the installation of IBM DB2 Connect on the remote Windows host is either 9.7 prior to Fix Pack 11 Special Build 36621, 10.1 prior to Fix Pack 6 Special Build 36610, 10.5 prior to Fix Pack 8 Special Build 36605, or 11.1.2 prior to Fix Pack 2. It is, therefore, affected by the following vulnerabilities : - A buffer overflow condition exists due to improper validation of user-supplied input. A local attacker can exploit this to overwrite DB2 files or cause a denial of service condition. (CVE-2017-1105) - A stack-based buffer overflow condition exists in the Command Line Process (CLP) due to improper bounds checking. A local attacker can exploit this to execute arbitrary code. (CVE-2017-1297)
