Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU7689

Risk: High

CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-0261

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code.

The weakness exists due to integer signedness error in the mobility_opt_print function in the IPv6 mobility printer A remote attacker can supply a negative length value, trigger out-of-bounds read, cause the system crash and possibly execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise

Mitigation

Update the affected package to version: 4.3.0-1+deb7u2, 4.6.2-4, 4.6.2-4

Vulnerable software versions

Debian 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.

2) Out-of-bounds write

EUVDB-ID: #VU7688

Risk: High

CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2015-2153

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code.

The weakness exists due to an error in the rpki_rtr_pdu_print function in print-rpki-rtr.c in the TCP printer. A remote attacker can supply a specially crafted header length in an RPKI-RTR Protocol Data Unit (PDU), trigger out-of-bounds read or write and cause the system crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update the affected package to version: 4.3.0-1+deb7u2, 4.6.2-4, 4.6.2-4

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, proof of concept for this vulnerability is available.

3) Out-of-bounds read

EUVDB-ID: #VU7687

Risk: Medium

CVSSv3.1: 7.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2015-2154

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to an error in the osi_print_cksum function in print-isoclns.c in the ethernet printer. A remote attacker can send a specially crafted length offset or base pointer checksum value, trigger out-of-bounds read and cause the system to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

Update the affected package to version: 4.3.0-1+deb7u2, 4.6.2-4, 4.6.2-4
