Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU23042

Risk: High

CVSSv4.0: 6.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-8675

CWE-ID: CWE-121 - Stack-based buffer overflow

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 when processing SNMP requests within the asn1_get_type() function in cups/snmp.c. A remote attacker can send a specially crafted SNMP request to the CUPS service, trigger stack-based buffer overflow 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 packages.

Vulnerable software versions

2) Stack-based buffer overflow

EUVDB-ID: #VU23040

Risk: High

CVSSv4.0: 5.9 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-8696

CWE-ID: CWE-121 - Stack-based buffer overflow

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 when processing SNMP requests within the asn1_get_packed() function in cups/snmp.c. A remote attacker with access to the the SNMP service can send a specially crafted request to the application, trigger a stack-based buffer oveflow 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 packages.
