Name of the Vulnerable Software and Affected Versions libsndfile versions 1.0.28

Description The issue is related to a buffer over-read in the i2alaw array function, which can lead to a denial of service. This can potentially allow a remote attacker to access confidential information or cause a service disruption. The i2ulaw array function is also mentioned as being related to a buffer data boundary issue, which can be exploited by a remote attacker.

Recommendations For libsndfile version 1.0.28, consider disabling the i2alaw array function as a temporary workaround until a patch is available. Restrict access to the vulnerable alaw.c module to minimize the risk of exploitation. Avoid using the i2ulaw array function in affected API endpoints until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
