Vulnerabilities > CVE-2014-2098 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Ffmpeg
Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
libavcodec/wmalosslessdec.c in FFmpeg before 2.1.4 uses an incorrect data-structure size for certain coefficients, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted WMA data.
Vulnerable Configurations
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.

(CVE-2012-2795). libavcodec/wmalosslessdec.c in FFmpeg before 2.1.4 uses an incorrect data-structure size for certain coefficients, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted WMA data (CVE-2014-2098). The msrle_decode_frame function in libavcodec/msrle.c in FFmpeg before 2.1.4 does not properly calculate line sizes, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Microsoft RLE video data (CVE-2014-2099). The mpegts_write_pmt function in the MPEG2 transport stream (aka DVB) muxer (libavformat/mpegtsenc.c) in FFmpeg, possibly 2.1 and earlier, allows remote attackers to have unspecified impact and vectors, which trigger an out-of-bounds write (CVE-2014-2263). A use-after-free vulnerability in FFmpeg before 1.1.9 involving seek operations on video data could allow remote attackers to cause a denial of service (CVE-2012-5150). An integer overflow can occur when processing any variant of a literal run in the av_lzo1x_decode function (CVE-2014-4609, CVE-2014-4610). The updated packages have been upgraded to the 0.10.14 version which is not vulnerable to these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 76437 published 2014-07-10 reporter This script is Copyright (C) 2014-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/76437 title Mandriva Linux Security Advisory : ffmpeg (MDVSA-2014:129) NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-201603-06.NASL description The remote host is affected by the vulnerability described in GLSA-201603-06 (FFmpeg: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in FFmpeg.
