Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU72506

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-0461

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the Upper Level Protocol (ULP) subsystem in Linux kernel caused by improper handling of sockets entering the LISTEN state in certain protocols. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

3) Out-of-bounds read

EUVDB-ID: #VU84353

Risk: Medium

CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-39197

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the Netfilter Connection Tracking (conntrack) in the Linux kernel in the nf_conntrack_dccp_packet() function in net/netfilter/nf_conntrack_proto_dccp.c. A remote attacker can send specially crafted DCCP packets to the system, trigger an out-of-bounds read error and read contents of memory on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.

5) Out-of-bounds write

EUVDB-ID: #VU84354

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-45863

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the fill_kobj_path() function in lib/kobject.c. A local user can can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel to the latest version.

6) Buffer overflow

EUVDB-ID: #VU83381

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-45871

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the IGB driver in drivers/net/ethernet/intel/igb/igb_main.c when handling frames larger than the MTU. A remote attacker can send specially crafted traffic to the system, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package the Linux Kernel to the latest version.
