1Security Handling 2================= 3 4Security Disclosures 5-------------------- 6 7We disclose all security vulnerabilities we find or are advised about that are 8relevant for ARM Trusted Firmware (TF). We encourage responsible disclosure of 9vulnerabilities and inform users as best we can about all possible issues. 10 11We disclose TF vulnerabilities as Security Advisories. These are listed at the 12bottom of this page and announced as issues in the `GitHub issue tracker`_ with 13the "security-advisory" tag. You can receive notification emails for these by 14watching that project. 15 16Found a Security Issue? 17----------------------- 18 19Although we try to keep TF secure, we can only do so with the help of the 20community of developers and security researchers. 21 22If you think you have found a security vulnerability, please *do not* report it 23in the `GitHub issue tracker`_. Instead send an email to 24trusted-firmware-security@arm.com 25 26Please include: 27 28* Trusted Firmware version (or commit) affected 29 30* A description of the concern or vulnerability 31 32* Details on how to replicate the vulnerability, including: 33 34 - Configuration details 35 36 - Proof of concept exploit code 37 38 - Any additional software or tools required 39 40We recommend using `this PGP/GPG key`_ for encrypting the information. This key 41is also available at http://keyserver.pgp.com and LDAP port 389 of the same 42server. The fingerprint for this key is: 43 44:: 45 46 1309 2C19 22B4 8E87 F17B FE5C 3AB7 EFCB 45A0 DFD0 47 48If you would like replies to be encrypted, please provide your public key. 49 50Please give us the time to respond to you and fix the vulnerability before going 51public. We do our best to respond and fix any issues quickly. We also need to 52ensure providers of products that use TF have a chance to consider the 53implications of the vulnerability and its remedy. 54 55Afterwards, we encourage you to write-up your findings about the TF source code. 56 57Attribution 58----------- 59 60We will name and thank you in the ``change-log.rst`` distributed with the source 61code and in any published security advisory. 62 63Security Advisories 64------------------- 65 66+-----------+------------------------------------------------------------------+ 67| ID | Title | 68+===========+==================================================================+ 69| `TFV-1`_ | Malformed Firmware Update SMC can result in copy of unexpectedly | 70| | large data into secure memory | 71+-----------+------------------------------------------------------------------+ 72| `TFV-2`_ | Enabled secure self-hosted invasive debug interface can allow | 73| | normal world to panic secure world | 74+-----------+------------------------------------------------------------------+ 75| `TFV-3`_ | RO memory is always executable at AArch64 Secure EL1 | 76+-----------+------------------------------------------------------------------+ 77| `TFV-4`_ | Malformed Firmware Update SMC can result in copy or | 78| | authentication of unexpected data in secure memory in AArch32 | 79| | state | 80+-----------+------------------------------------------------------------------+ 81| `TFV-5`_ | Not initializing or saving/restoring PMCR_EL0 can leak secure | 82| | world timing information | 83+-----------+------------------------------------------------------------------+ 84| `TFV-6`_ | Arm Trusted Firmware exposure to speculative processor | 85| | vulnerabilities using cache timing side-channels | 86+-----------+------------------------------------------------------------------+ 87| `TFV-7`_ | Trusted Firmware-A exposure to cache speculation vulnerability | 88| | Variant 4 | 89+-----------+------------------------------------------------------------------+ 90| `TFV-8`_ | Not saving x0 to x3 registers can leak information from one | 91| | Normal World SMC client to another | 92+-----------+------------------------------------------------------------------+ 93 94.. _GitHub issue tracker: https://github.com/ARM-software/tf-issues/issues 95.. _this PGP/GPG key: security-reporting.asc 96.. _TFV-1: ./security_advisories/security-advisory-tfv-1.rst 97.. _TFV-2: ./security_advisories/security-advisory-tfv-2.rst 98.. _TFV-3: ./security_advisories/security-advisory-tfv-3.rst 99.. _TFV-4: ./security_advisories/security-advisory-tfv-4.rst 100.. _TFV-5: ./security_advisories/security-advisory-tfv-5.rst 101.. _TFV-6: ./security_advisories/security-advisory-tfv-6.rst 102.. _TFV-7: ./security_advisories/security-advisory-tfv-7.rst 103.. _TFV-8: ./security_advisories/security-advisory-tfv-8.rst 104
