Name of the Vulnerable Software and Affected Versions Cisco libSRTP versions prior to 1.5.3

Description The issue is related to the encryption-processing feature in Cisco libSRTP, which allows remote attackers to cause a denial of service via crafted fields in SRTP packets. This is due to improper input validation of certain fields of SRTP packets. An attacker could exploit this vulnerability by sending a crafted SRTP packet designed to trigger the issue to an affected device. The impact of this vulnerability on Cisco products may vary depending on the affected product.

Recommendations For versions prior to 1.5.3, update to version 1.5.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the encryption processing subsystem of libSRTP to minimize the risk of exploitation.
