Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2024-57256)

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

The vulnerability exists due to integer overflow within the ext4fs_read_symlink() function. A local user can use a specially crafted ext4 filesystem to trigger an integer overflow and execute arbitrary code with elevated privileges.



2) Integer overflow (CVE-ID: CVE-2024-57254)

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

The vulnerability exists due to integer overflow within the sqfs_inode_size() function when calculating a symlink size. A local user can create a specially crafted symbolic link, trigger an integer overflow and execute arbitrary code with elevated privileges.


3) Integer overflow (CVE-ID: CVE-2024-57255)

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

The vulnerability exists due to integer overflow within the sqfs_resolve_symlink() function. A local user can use a specially crafted squashfs filesystem with an inode size of 0xffffffff to trigger integer overflow and execute arbitrary code on the target system.


4) Resource exhaustion (CVE-ID: CVE-2024-57257)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in the sqfs_size() function. A local user can use a specially crafted squashfs filesystem with deep symlink nesting to trigger resource exhaustion and perform a denial of service (DoS) attack.


5) Integer overflow (CVE-ID: CVE-2024-57258)

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

The vulnerability exists due to integer overflow. A local user can use a specially crafted squashfs filesystem to trigger integer overflow and execute arbitrary code on the target system.


6) Off-by-one (CVE-ID: CVE-2024-57259)

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

The vulnerability exists due to an off-by-one error within the sqfs_search_dir() function. A local user can trigger memory corruption for squashfs directory listing and execute arbitrary code with elevated privileges.
