Description
A flaw was found in the libsndfile library. An integer overflow in the IMA ADPCM codec can occur when a specially crafted WAV audio file is processed, specifically with malicious samplesperblock and blocks values. This can lead to a heap-based buffer overflow, causing a crash to the application linked to the library and memory corruption.
Statement
To exploit this issue, an attacker needs to be able to process a malicious WAV file with an application linked to the libsndfile library.
Default Red Hat Enterprise Linux security features, including SELinux enforcement, Address Space Layout Randomization (ASLR) and NX (No-Execute) stack protection, significantly increase the difficulty of achieving arbitrary code execution, limiting the impact of this vulnerability.
Due to these reasons, this flaw has been rated with an important severity.
CVSS score applicability
The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
Mitigation
Do not process untrusted WAV files with the libsndfile library.
