Summary

Heap-based buffer overflow in the flac_buffer_copy function in libsndfile 1.0.17 and earlier might allow remote attackers to execute arbitrary code via a FLAC file with crafted PCM data containing a block with a size that exceeds the previous block size.

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 familyGentoo Local Security Checks
    NASL idGENTOO_GLSA-200710-04.NASL
    descriptionThe remote host is affected by the vulnerability described in GLSA-200710-04 (libsndfile: Buffer overflow) Robert Buchholz of the Gentoo Security team discovered that the flac_buffer_copy() function does not correctly handle FLAC streams with variable block sizes which leads to a heap-based buffer overflow (CVE-2007-4974). Impact : A remote attacker could exploit this vulnerability by enticing a user to open a specially crafted FLAC file or network stream with an application using libsndfile. This might lead to the execution of arbitrary code with privileges of the user playing the file. Workaround : There is no known workaround at this time.
