Security Bulletin

This security bulletin contains information about 9 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU44761

Risk: Medium

CVSSv3.1: 4.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:U/RC:C]

CVE-ID: CVE-2009-5063

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows context-dependent 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 (memory leak or segmentation fault) via a JPEG image containing an iCCP chunk with a negative embedded profile length.

Mitigation

Update the affected packages.
media-libs/libpng to version: 1.5.10

2) 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.

EUVDB-ID: #VU44882

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2011-2690

CWE-ID: CWE-120 - Buffer overflow
