Red Hat update for flash-plugin

1) Stack-based buffer overflow

EUVDB-ID: #VU5186

Risk: Critical

CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0498

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to stack-based buffer overflow when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Red Hat Enterprise Linux Desktop: 5 - 6

Red Hat Enterprise Linux Workstation: 6

Red Hat Enterprise Linux Server: 6.0 - v.5

2) Information disclosure

EUVDB-ID: #VU5187

Risk: High

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

CVE-ID: CVE-2014-0499

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to memory leak error when processing .swf files. A remote attacker can create a specially crafted Web page, trick the victim into visiting it, bypass the ASLR protection mechanism and defeat memory address layout randomization.

Successful exploitation of the vulnerability results in information disclosure on the vulnerable system.

Note: the vulnerability was being actively exploited.

Mitigation

Install updates from vendor's website.

3) Double free

EUVDB-ID: #VU5185

Risk: Critical

CVSSv3.1: 9.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]

CVE-ID: CVE-2014-0502

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to double free error when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.
