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.

Julien Tinnes reported that bip does not check the number of open file descriptors against FD_SETSIZE, resulting in a stack buffer overflow (CVE-2012-0806). Impact : A remote attacker could exploit these vulnerabilities to execute arbitrary code with the privileges of the user running the bip daemon, or cause a Denial of Service condition. Workaround : There is no known workaround at this time. last seen 2020-06-01 modified 2020-06-02 plugin id 57744 published 2012-01-31 reporter This script is Copyright (C) 2012-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/57744 title GLSA-201201-18 : bip: Multiple vulnerabilities NASL family Fedora Local Security Checks NASL id FEDORA_2012-0941.NASL description Add upstream patch to fix buffer overflow with too many open fd last seen 2020-03-17 modified 2012-02-06 plugin id 57829 published 2012-02-06 reporter This script is Copyright (C) 2012-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/57829 title Fedora 16 : bip-0.8.8-2.fc16 (2012-0941) NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_1C4CAB30546811E19FB7003067B2972C.NASL description Julien Tinnes reports, Bip doesn last seen 2020-06-01 modified 2020-06-02 plugin id 57908 published 2012-02-13 reporter This script is Copyright (C) 2012-2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/57908 title FreeBSD : bip -- buffer overflow (1c4cab30-5468-11e1-9fb7-003067b2972c)
