Alpine: multiple libtpms packages: security update to 0.9.7-r0

medium Tenable Cloud Security Plugin ID 427863

Description

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

 - Libtpms is a library that targets the integration of TPM functionality into hypervisors, primarily into
 Qemu. Libtpms, which is derived from the TPM 2.0 reference implementation code published by the Trusted
 Computing Group, is prone to a potential out of bounds (OOB) read vulnerability. The vulnerability occurs
 in the ‘CryptHmacSign’ function with an inconsistent pairing of the signKey and signScheme parameters,
 where the signKey is ALG_KEYEDHASH key and inScheme is an ECC or RSA scheme. The reported vulnerability is
 in the ‘CryptHmacSign’ function, which is defined in the "Part 4: Supporting Routines – Code" document,
 section "7.151 - /tpm/src/crypt/CryptUtil.c ". This vulnerability can be triggered from user-mode
 applications by sending malicious commands to a TPM 2.0/vTPM (swtpm) whose firmware is based on an
 affected TCG reference implementation. The effect on libtpms is that it will cause an abort due to the
 detection of the out-of-bounds access, thus for example making a vTPM (swtpm) unavailable to a VM. This
 vulnerability is fixed in 0.7.12, 0.8.10, 0.9.7, and 0.10.1. (CVE-2025-49133)
