VAR-201101-0006
Vulnerability from variot - Updated: 2025-04-11 22:50Memory leak in the gk_circuit_info_do_in_acf function in the H.323 implementation in Cisco IOS before 15.0(1)XA allows remote attackers to cause a denial of service (memory consumption) via a large number of calls over a long duration, as demonstrated by InterZone Clear Token (IZCT) test traffic, aka Bug ID CSCsz72535. Cisco IOS of H.323 Implementation gk_circuit_info_do_in_acf Function leaks memory and interferes with service operation (DoS) There is a vulnerability that becomes a condition. The problem is Bug ID CSCsz72535 It is a problem.Denial of service by a large number of long-term calls by third parties (DoS) There is a possibility of being put into a state. Cisco IOS is prone to a remote denial-of-service vulnerability. An attacker can exploit this issue to cause the affected device to consume an excessive amount of memory, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCsz72535. Cisco IOS is an operating system developed by Cisco in the United States for its network equipment
