This security bulletin contains information about 9 secuirty vulnerabilities.

1) Out-of-bounds write (CVE-ID: CVE-2024-45774)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when parsing JPEG files. A local user can trigger an out-of-bounds write and execute arbitrary code on the system.

2) Integer overflow (CVE-ID: CVE-2024-45778)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow when reading BFS filesystem. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.

3) Integer overflow (CVE-ID: CVE-2024-45779)

The vulnerability allows a local user to corrupt data.

The vulnerability exists due to integer overflow within the BFS filesystem driver. A local user can trigger an integer overflow and corrupt data.

4) Integer overflow (CVE-ID: CVE-2024-45780)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to integer overflow when handling tar files. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.

5) Heap-based buffer overflow (CVE-ID: CVE-2024-56737)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the fs/hfs.c when reading sblock data from HFS filesystem. A local user can trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.

6) Use-after-free (CVE-ID: CVE-2025-0622)
