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.

    descriptionThe version of VLC media player installed on the remote host is prior to 2.2.5. It is, therefore, affected by the multiple vulnerabilities : - A denial of service vulnerability exists within file plugins\audio_filter\libmpgatofixed32_plugin.dll when parsing media files due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to crash the application. (CVE-2017-9301) - A flaw exists, related to a ParseJSS null skip, when handling specially crafted subtitle files downloaded by the media player. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to execute arbitrary code. - A heap-based buffer overflow condition exists due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted AVI file, to execute arbitrary code. - A memory corruption issue exists when handling LPCM in VOB files. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to execute arbitrary code. - An exploitable vulnerability exists in plugins\codec\libflac_plugin.dll, allows remote attackers to cause denial of service (heap corruption and application crash) or possibly have unspecified other impact via a crafted FLAC file. (CVE-2017-9300). - An exploitable Heap out-of-bound read vulnerability exists in ParseJSS of VideoLan VLC. This is due to missing check of string termination allows attackers to read data beyond allocated memory and potentially crash the process via a crafted subtitles file. (CVE-2017-8313). - An exploitable heap based buffer overflow vulnerability exists in ParseJSS of VideoLan VLC. This is due to skipping NULL terminator in an input string allows attackers to execute arbitrary code via a crafted subtitles file. (CVE-2017-8311). - An exploitable Heap out-of-bound read vulnerability exists in CreateHtmlSubtitle of VideoLan VLC.
