Security Bulletin: Due to use of Expat, IBM Tivoli Network Manager is vulnerable to arbiraty code execution (CVE-2022-23990 and CVE-2022-23852)

Summary

When Expat (also known as libexpat) is used by IBM Tivoli Network Manager ( ITNM ), it could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in the XML_GetBuffer function. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system. (CVE-2022-23990 and CVE-2022-23852)
