Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU42671

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-4115

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Buffer overflow in the idnsALookup function in dns_internal.cc in Squid 3.2 through 3.2.11 and 3.3 through 3.3.6 allows remote attackers to cause a denial of service (memory corruption and server termination) via a long name in a DNS lookup request.

Mitigation

Update the affected packages:

i686:
    squid-3.1.10-29.17.amzn1.i686
    squid-debuginfo-3.1.10-29.17.amzn1.i686

src:
    squid-3.1.10-29.17.amzn1.src

x86_64:
    squid-3.1.10-29.17.amzn1.x86_64
    squid-debuginfo-3.1.10-29.17.amzn1.x86_64

2) Input validation error

EUVDB-ID: #VU32538

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0128

CWE-ID: CWE-20 - Improper input validation
