Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU32533
Risk: Medium
CVSSv3.1: 4.6 [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-2013-7353
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Integer overflow in the png_set_unknown_chunks function in libpng/pngset.c in libpng before 1.5.14beta08. A remote attacker can use a crafted image 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.
MitigationInstall updates from vendor's repository.

2) Input validation error
EUVDB-ID: #VU33845
Risk: Medium
CVSSv3.1: 4.6 [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-2013-7354
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to perform service disruption.
Multiple integer overflows in libpng before 1.5.14rc03 allow remote attackers to cause a denial of service (crash) via a crafted image to the (1) png_set_sPLT or (2) png_set_text_2 function, which triggers a heap-based buffer overflow.

3) Input validation error
EUVDB-ID: #VU19180
Risk: Low
CVSSv3.1: 2.5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-12652
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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 libpng when checking the chuck length against the user limit. A remote attacker can supply a specially crafted PNG image and crash the affected application.
