Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU66220
Risk: High
CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-0529
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing zip archives during the conversion of a UTF-8 string to a local string. A remote attacker can create a specially crafted zip file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
MitigationUpdate the affected package unzip to the latest version.

2) Heap-based buffer overflow
EUVDB-ID: #VU63289
Risk: High
CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-0530
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package unzip to the latest version.
