It is another one of those weeks when there are a slew of security vulnerabilities to attend to. Four that we know of, to be precise.

First, there is Security Bulletin: IBM WebSphere Application Server Liberty is vulnerable to a denial of service due to Google protobuf-java (CVE-2022-3171, CVE-2022-3509), which you can read more about at this link. This vulnerability affects IBM WebSphere Application Server Liberty versions 21.0.0.2 through 22.0.0.12.

Second, there is Security Bulletin: ISC BIND on IBM i is vulnerable to denial of service due to memory leaks and a flaw in resolver code (CVE-2022-2795, CVE-2022-38177, CVE-2022-38178), which you can find out more about here. The IBM i PTF numbers contain the fix for the vulnerabilities:

7.5 SI81706
7.4 SI81707
7.3 SI81708
7.2 SI81709

Third, there is Security Bulletin: Digital Certificate Manager for IBM i is vulnerable to cross-site scripting (CVE-2022-34358), which you can see more about here. The IBM i PTF numbers contain the fix for the vulnerability:

7.5 SI80415
7.4 SI80414

Additional URLs were identified that can be used for a cross-site scripting attack resulting in superseded PTFs. The IBM i superseding PTF numbers contain the fix for the vulnerability:
