SB2025030436 - openEuler 22.03 LTS SP3 update for uboot-tools

Description

This security bulletin contains information about 6 vulnerabilities.

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

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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.

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

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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.

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

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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.

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

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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)

CWE-ID: CWE-193 - Off-by-one Error

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

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.
