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.

    descriptionlibmspack was updated to fix security issues. These security issues were fixed : - CVE-2014-9732: The cabd_extract function in cabd.c in libmspack did not properly maintain decompression callbacks in certain cases where an invalid file follows a valid file, which allowed remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted CAB archive (bnc#934524). - CVE-2015-4467: The chmd_init_decomp function in chmd.c in libmspack did not properly validate the reset interval, which allowed remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted CHM file (bnc#934525). - CVE-2015-4468: Multiple integer overflows in the search_chunk function in chmd.c in libmspack allowed remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted CHM file (bnc#934526). - CVE-2015-4469: The chmd_read_headers function in chmd.c in libmspack did not validate name lengths, which allowed remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted CHM file (bnc#934526). - CVE-2015-4470: Off-by-one error in the inflate function in mszipd.c in libmspack allowed remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted CAB archive (bnc#934527). - CVE-2015-4471: Off-by-one error in the lzxd_decompress function in lzxd.c in libmspack allowed remote attackers to cause a denial of service (buffer under-read and application crash) via a crafted CAB archive (bnc#934528). - CVE-2015-4472: Off-by-one error in the READ_ENCINT macro in chmd.c in libmspack allowed remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted CHM file (bnc#934529).

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
