Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU33144

Risk: Medium

CVSSv4.0: 5.7 [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:Green]

CVE-ID: CVE-2014-8139

CWE-ID: CWE-122 - Heap-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 in Heap-based buffer overflow in the CRC32 verification in Info-ZIP UnZip 6.0 and earlier. A remote attacker can use a crafted zip file in the -t command argument to the unzip command. to trigger 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.

Mitigation

Update the affected package infozip.

Vulnerable software versions

3) Heap-based buffer overflow

EUVDB-ID: #VU33146

Risk: Medium

CVSSv4.0: 5.7 [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:Green]

CVE-ID: CVE-2014-8141

CWE-ID: CWE-122 - Heap-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 in Heap-based buffer overflow in the getZip64Data function in Info-ZIP UnZip 6.0 and earlier. A remote attacker can use a crafted zip file in the -t command argument to the unzip command. to trigger 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.

4) Input validation error

EUVDB-ID: #VU18051

Risk: Medium

CVSSv4.0: 5.2 [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:P/U:Green]

CVE-ID: CVE-2016-9844

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the zi_short() function in zipinfo.c when processing a large compression method value in the central directory file header. A remote attacker can pass a specially crafted array to the application and trigger denial of service (DoS) condition.

Mitigation

Update the affected package infozip.
