Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU7689

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

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 packages.

2) Out-of-bounds read

EUVDB-ID: #VU7687

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

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 packages.
