Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Integer overflow

EUVDB-ID: #VU105267

Risk: Low

CVSSv4.0: 5.9 [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]

CVE-ID: CVE-2024-57256

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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.


Mitigation

Install updates from vendor's website.

2) Integer overflow

EUVDB-ID: #VU105292

Risk: Low

CVSSv4.0: 5.9 [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]

CVE-ID: CVE-2024-57254

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

3) Integer overflow

EUVDB-ID: #VU105293

Risk: Low

CVSSv4.0: 5.9 [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]

CVE-ID: CVE-2024-57255

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.
