1) Integer overflow

EUVDB-ID: #VU14104

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-0360

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to integer overflow when handling malicious input. A remote attacker can trick the victim into opening a specially crafted file, trigger an infinite loop and cause the service to crash.

Mitigation

Update the affected packages.

3) Out-of-bounds read

EUVDB-ID: #VU11136

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-1000085

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

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the xar_hash_check() function due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted XAR file, trick the victim into opening it, trigger out-of-bounds heap memory read and cause the service to crash.

Mitigation

Update the affected packages.
