Re: [TF-M] Security vulnerability notice - SVC handler fetches incorrect caller stack pointer under specific cases.

by Kumar Gala

Agreed, I think it's a great thing for the SC to take up and make a policy on. Will add 2 cents: * Being a security focused project, I think its import that at least there is a patch release for the most recent officially released version, regardless of when the next release of TFM might be released. * Maybe looking at what policy a project like mbedtls has as a starting point. - k > On Mar 5, 2021, at 12:34 PM, Anton Komlev via TF-M <tf-m(a)lists.trustedfirmware.org> wrote: > > Hi Kumar, All, > > Thanks for bringing this topic up. > At the moment there is no plan for issuing the release v1.2.1 because of lack of policy for such hot fix releases.

Re: [TF-M] Security vulnerability notice - SVC handler fetches incorrect caller stack pointer under specific cases.

by Anton Komlev

Hi Kumar, All, Thanks for bringing this topic up. At the moment there is no plan for issuing the release v1.2.1 because of lack of policy for such hot fix releases. The release policy upgrade proposal shall be reviewed and agreed in the Steering Committee with the main questions: 1. What is the hot fix baseline? 2. What is the testing scope of the fix? 3. On which platform(s) the fix shall be tested? The policy is under discussion and the community input is welcome. Please share your thoughts on the topic. The release v1.3.0 is expected by end of March-beginning of April, which will include the fix.

Re: [TF-M] Review on Firmware Update service in TF-M

by Sherry Zhang

Hi, Add some technical details. The newly added Firmware Update service provides the functionality of updating firmware images. It provides a standard interface for updating firmware and it is designed as platform/bootloader independent. The nonsecure application can call this service to achieve the firmware update by integrating TF-M with, for example, OTA library in the nonsecure side. The implementation provides a shim layer between the bootloader and the firmware update partition. Other bootloaders besides MCUboot should be easily ported with this partition. Any comment is very welcomed!

I would like to ask you to review this patchset if you are interested in it. Top of the patchset: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/7883 Regards, Sherry Zhang
