Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU70413

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2015-0209

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c. A remote attacker can perform a denial of service (DoS) attack or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 22

mingw-openssl: before 1.0.2a-1.fc22

CPE2.3 External links

https://bodhi.fedoraproject.org/updates/FEDORA-2015-6951


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Input validation error

EUVDB-ID: #VU70415

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2015-0293

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 the SSLv2 implementation. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
