Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU5214

Risk: Medium

CVSSv4.0: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:A/U:Green]

CVE-ID: CVE-2014-3566

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.

Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.

Note: The vulnerability is known as POODLE.

Mitigation

Update the affected packages.
mail-client/claws-mail to version: 3.13.2

Vulnerable software versions

Gentoo Linux: All versions

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. However, a fully functional exploit for this vulnerability is available.

2) Stack-based buffer overflow

EUVDB-ID: #VU32283

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-2015-8614

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 vulnerability exists due to a boundary error when processing a crafted email, involving Japanese character set conversion. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.
mail-client/claws-mail to version: 3.13.2

3) Stack-based buffer overflow

EUVDB-ID: #VU40397

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-2015-8708

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 vulnerability exists due to a boundary error within the conv_euctojis function in codeconv.c when processing a crafted email, involving Japanese character set conversion. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-8614. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.
