Description

This security bulletin contains information about 4 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2018-1000035)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to heap-based buffer overflow in the processing of password-protected archives. A remote attacker can trigger memory corruption and cause the service to crash or execute arbitrary code with elevated privileges.

2) Buffer overflow (CVE-ID: CVE-2018-1000031)

CWE-ID: CWE-119 - Memory corruption

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


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

A heap-based buffer overflow exists in Info-Zip UnZip version 6.10c22 that allows an attacker to perform a denial of service or to possibly achieve code execution.


3) Buffer overflow (CVE-ID: CVE-2018-1000032)

CWE-ID: CWE-119 - Memory corruption

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


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

A heap-based buffer overflow exists in Info-Zip UnZip version 6.10c22 that allows an attacker to perform a denial of service or to possibly achieve code execution.


4) Out-of-bounds read (CVE-ID: CVE-2018-1000033)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote non-authenticated attacker to #BASIC_IMPACT#.

An out-of-bounds read exists in Info-Zip UnZip version 6.10c22 that allows an attacker to perform a denial of service and read sensitive memory.
