Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU32710

Risk: Low

CVSSv4.0: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:A/U:Clear]

CVE-ID: CVE-2013-1899

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows remote attackers to cause a denial of service (file corruption), and allows remote authenticated users to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can modify configuration settings and execute arbitrary code, via a connection request using a database name that begins with a "-" (hyphen).

Mitigation

Update the affected packages.

Vulnerable software versions

SUSE Linux: 11

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated privileged user via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, a fully functional exploit for this vulnerability is available.

2) Input validation error

EUVDB-ID: #VU33905

Risk: Medium

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2013-1900

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote #AU# to execute arbitrary code.

PostgreSQL 9.2.x before 9.2.4, 9.1.x before 9.1.9, 9.0.x before 9.0.13, and 8.4.x before 8.4.17, when using OpenSSL, generates insufficiently random numbers, which might allow remote authenticated users to have an unspecified impact via vectors related to the "contrib/pgcrypto functions." Per http://www.ubuntu.com/usn/USN-1789-1/ "A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.10 Ubuntu 12.04 LTS Ubuntu 11.10 Ubuntu 10.04 LTS Ubuntu 8.04 LTS"

Mitigation

Update the affected packages.

3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU32711

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2013-1901

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote #AU# to manipulate data.

PostgreSQL 9.2.x before 9.2.4 and 9.1.x before 9.1.9 does not properly check REPLICATION privileges, which allows remote authenticated users to bypass intended backup restrictions by calling the (1) pg_start_backup or (2) pg_stop_backup functions. Per http://www.ubuntu.com/usn/USN-1789-1/ "A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.10 Ubuntu 12.04 LTS Ubuntu 11.10 Ubuntu 10.04 LTS Ubuntu 8.04 LTS"

Mitigation
