CVE-2023-1018

A library providing TPM functionality for VMs. Targeted for integration into Qemu.

Security Fix(es):

An out-of-bounds read vulnerability exists in TPM2.0's Module Library allowing a 2-byte read past the end of a TPM2.0 command in the CryptParameterDecryption routine. An attacker who can successfully exploit this vulnerability can read or access sensitive data stored in the TPM.(CVE-2023-1018)

An out-of-bounds write vulnerability exists in TPM2.0's Module Library allowing writing of a 2-byte data past the end of TPM2.0 command in the CryptParameterDecryption routine. An attacker who can successfully exploit this vulnerability can lead to denial of service (crashing the TPM chip/process or rendering it unusable) and/or arbitrary code execution in the TPM context.(CVE-2023-1017)

Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.

Security Fix(es):

• ntfs-3g: heap-based buffer overflow in ntfsck (CVE-2021-46790)

• QEMU: VNC: integer underflow in vnc_client_cut_text_ext leads to CPU exhaustion (CVE-2022-3165)

• ntfs-3g: crafted NTFS image can cause heap exhaustion in ntfs_get_attribute_value (CVE-2022-30784)

• ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in ntfs_names_full_collate (CVE-2022-30786)

• ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in ntfs_mft_rec_alloc (CVE-2022-30788)

• ntfs-3g: crafted NTFS image can cause a heap-based buffer overflow in ntfs_check_log_client_array (CVE-2022-30789)

• tpm2: TCG TPM2.0 implementations vulnerable to memory corruption (CVE-2023-1018)

These are all security issues fixed in the libtpms-devel-0.9.6-1.1 package on the GA media of openSUSE Tumbleweed.

This update for libtpms fixes the following issues:

• CVE-2023-1017: Fixed out-of-bounds write in CryptParameterDecryption (bsc#1206022).
• CVE-2023-1018: Fixed out-of-bounds read in CryptParameterDecryption (bsc#1206023).

Francisco Falcon discovered that Libtpms did not properly manage memory when performing certain cryptographic operations. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2023-1017, CVE-2023-1018)

It was discovered that Libtpms did not properly manage memory when handling certain commands. An attacker could possibly use this issue to cause a denial of service.
