Attack vector
UNKNOWN Attack complexity
UNKNOWN Privileges required
UNKNOWN Confidentiality impact
UNKNOWN Integrity impact
UNKNOWN Availability impact
UNKNOWN Summary
Multiple buffer overflows in Free Lossless Audio Codec (FLAC) libFLAC before 1.2.1 allow user-assisted remote attackers to execute arbitrary code via large (1) Metadata Block Size, (2) VORBIS Comment String Size, (3) Picture Metadata MIME-TYPE Size, (4) Picture Description Size, (5) Picture Data Length, (6) Padding Length, and (7) PICTURE Metadata width and height values in a .FLAC file, which result in a heap-based overflow; and large (8) VORBIS Comment String Size Length, (9) Picture MIME-Type, (10) Picture MIME-Type URL, and (11) Picture Description Length values in a .FLAC file, which result in a stack-based overflow. NOTE: some of these issues may overlap CVE-2007-4619.

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 CentOS Local Security Checks NASL id CENTOS_RHSA-2007-0975.NASL description An updated flac package to correct a security issue is now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having important security impact by the Red Hat Security Response Team. FLAC is a Free Lossless Audio Codec. The flac package consists of a FLAC encoder and decoder in library form, a program to encode and decode FLAC files, a metadata editor for FLAC files and input plugins for various music players. A security flaw was found in the way flac processed audio data. An attacker could create a carefully crafted FLAC audio file in such a way that it could cause an application linked with flac libraries to crash or execute arbitrary code when it was opened. (CVE-2007-4619) Users of flac are advised to upgrade to this updated package, which contains a backported patch that resolves this issue. last seen 2020-06-01 modified 2020-06-02 plugin id 27539 published 2007-10-25 reporter This script is Copyright (C) 2007-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/27539 title CentOS 4 / 5 : flac (CESA-2007:0975) NASL family Debian Local Security Checks NASL id DEBIAN_DSA-1469.NASL description Sean de Regge and Greg Linares discovered multiple heap and stack based buffer overflows in FLAC, the Free Lossless Audio Codec, which could lead to the execution of arbitrary code. last seen 2020-06-01 modified 2020-06-02 plugin id 30061 published 2008-01-27 reporter This script is Copyright (C) 2008-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/30061 title Debian DSA-1469-1 : flac - several vulnerabilities NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2007-0975.NASL description An updated flac package to correct a security issue is now available for Red Hat Enterprise Linux 4 and 5.
