Amazon Linux AMI update for unzip

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

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.
