openEuler update for syslinux

1) Input validation error

EUVDB-ID: #VU44881

Risk: Medium

CVSSv3.1: 5.7 [AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2011-2501

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression.

Mitigation

Install updates from vendor's repository.

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

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 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.

Mitigation

Install updates from vendor's repository.

14) Out-of-bounds read

EUVDB-ID: #VU96991

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2004-0421

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted PNG file, trick the victim into opening it, trigger an out-of-bounds read error and crash the application.

Mitigation

Install updates from vendor's repository.

15) Integer overflow

EUVDB-ID: #VU44269

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-2011-3026

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

Integer overflow in libpng, as used in Google Chrome before 17.0.963.56, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that trigger an integer truncation.

Mitigation

Install updates from vendor's repository.
