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.

NASL family Scientific Linux Local Security Checks NASL id SL_20150611_WPA_SUPPLICANT_ON_SL7_X.NASL description A buffer overflow flaw was found in the way wpa_supplicant handled SSID information in the Wi-Fi Direct / P2P management frames. A specially crafted frame could allow an attacker within Wi-Fi radio range to cause wpa_supplicant to crash or, possibly, execute arbitrary code. (CVE-2015-1863) An integer underflow flaw, leading to a buffer over-read, was found in the way wpa_supplicant handled WMM Action frames. A specially crafted frame could possibly allow an attacker within Wi-Fi radio range to cause wpa_supplicant to crash.

More information on this vulnerability is provided by upstream at https://w1.fi/security/2015-1/wpa_supplicant-p2p-ssid-overflow.txt . An extract : Attacker (or a system controlled by the attacker) needs to be within radio range of the vulnerable system to send a suitably constructed management frame that triggers a P2P peer device information to be created or updated. The vulnerability is easiest to exploit while the device has started an active P2P operation (e.g., has ongoing P2P_FIND or P2P_LISTEN control interface command in progress). However, it may be possible, though significantly more difficult, to trigger this even without any active P2P operation in progress. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-05 modified 2015-04-29 plugin id 83129 published 2015-04-29 reporter This script is Copyright (C) 2015-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/83129 title Fedora 22 : wpa_supplicant-2.3-3.fc22 (2015-6898) NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_CB9D2FCDEB4711E4B03E002590263BF5.NASL description Jouni Malinen reports : A vulnerability was found in how wpa_supplicant uses SSID information parsed from management frames that create or update P2P peer entries (e.g., Probe Response frame or number of P2P Public Action frames). SSID field has valid length range of 0-32 octets. However, it is transmitted in an element that has a 8-bit length field and potential maximum payload length of 255 octets. wpa_supplicant was not sufficiently verifying the payload length on one of the code paths using the SSID received from a peer device. This can result in copying arbitrary data from an attacker to a fixed length buffer of 32 bytes (i.e., a possible overflow of up to 223 bytes). The SSID buffer is within struct p2p_device that is allocated from heap. The overflow can override couple of variables in the struct, including a pointer that gets freed. In addition about 150 bytes (the exact length depending on architecture) can be written beyond the end of the heap allocation. This could result in corrupted state in heap, unexpected program behavior due to corrupted P2P peer device information, denial of service due to wpa_supplicant process crash, exposure of memory contents during GO Negotiation, and potentially arbitrary code execution. Vulnerable versions/configurations wpa_supplicant v1.0-v2.4 with CONFIG_P2P build option enabled (which is not compiled by default). Attacker (or a system controlled by the attacker) needs to be within radio range of the vulnerable system to send a suitably constructed management frame that triggers a P2P peer device information to be created or updated. The vulnerability is easiest to exploit while the device has started an active P2P operation (e.g., has ongoing P2P_FIND or P2P_LISTEN control interface command in progress). However, it may be possible, though significantly more difficult, to trigger this even without any active P2P operation in progress. last seen 2020-06-01 modified 2020-06-02 plugin id 83082 published 2015-04-27 reporter This script is Copyright (C) 2015-2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/83082 title FreeBSD : wpa_supplicant -- P2P SSID processing vulnerability (cb9d2fcd-eb47-11e4-b03e-002590263bf5) NASL family Fedora Local Security Checks NASL id FEDORA_2015-6952.NASL description This update addresses a security vulnerability identified as CVE-2015-1863 .
