Oracle Linux: CVE-2022-23645: ELSA-2022-7472: virt:ol and virt-devel:ol security, bug fix, and enhancement update (LOW) (Multiple Advisories)

swtpm is a libtpms-based TPM emulator with socket, character device, and Linux CUSE interface. Versions prior to 0.5.3, 0.6.2, and 0.7.1 are vulnerable to out-of-bounds read. A specially crafted header of swtpm's state, where the blobheader's hdrsize indicator has an invalid value, may cause an out-of-bounds access when the byte array representing the state of the TPM is accessed. This will likely crash swtpm or prevent it from starting since the state cannot be understood. Users should upgrade to swtpm v0.5.3, v0.6.2, or v0.7.1 to receive a patch. There are currently no known workarounds.
An out-of-bounds read vulnerability was found in swtpm. The vulnerability exists due to a boundary condition when the byte array representing the state of the TPM is accessed. This flaw allows an attacker to send a specially crafted header, triggering an out-of-bounds read access on the byte array containing the TPM's state. This issue can crash swtpm or prevent it from starting.
