Alpine: multiple arm-trusted-firmware packages: security update to 2.8.14-r0

medium Tenable Cloud Security Plugin ID 427742

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Trusted Firmware-A (TF-A) before 2.10 has a potential read out-of-bounds in the SDEI service. The input
 parameter passed in register x1 is not validated well enough in the function sdei_interrupt_bind. The
 parameter is passed to a call to plat_ic_get_interrupt_type. It can be any arbitrary value passing checks
 in the function plat_ic_is_sgi. A compromised Normal World (Linux kernel) can enable a root-privileged
 attacker to issue arbitrary SMC calls. Using this primitive, he can control the content of registers x0
 through x6, which are used to send parameters to TF-A. Out-of-bounds addresses can be read in the context
 of TF-A (EL3). Because the read value is never returned to non-secure memory or in registers, no leak is
 possible. An attacker can still crash TF-A, however. (CVE-2023-49100)
