Name of the Vulnerable Software and Affected Versions libsndfile version 1.0.28

Description The issue is related to a buffer over-read in the i2ulaw array function, which can lead to a denial of service. This can be exploited by a remote attacker to cause a service disruption. The i2ulaw array function in the ulaw.c file is specifically affected.
