Title
Opensc: multiple memory issues with pkcs15-init (enrollment tool)
Summary
Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow
compromise key generation, certificate loading, and other card management operations during enrollment.
Severity ?
5.4 (Medium)

Title
Opensc: potential pin bypass when card tracks its own login state
Summary
A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.

Title
Qemu: improper ide controller reset can lead to mbr overwrite
Summary
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.

Title
Qemu: improper ide controller reset can lead to mbr overwrite
Summary
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
