| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
net-snmp versions 5.1.2 through 5.3.1
net-snmp-devel versions 5.1.2 through 5.3.1
net-snmp-libs versions 5.1.2 through 5.3.1
net-snmp-utils versions 5.1.2 through 5.3.1
Description
The issue is related to an integer overflow in the
netsnmp create subtree cache function, which can be triggered by a crafted SNMP GETBULK request. This may cause a denial of service (crash) due to a heap-based buffer overflow. The vulnerability can be exploited remotely, potentially leading to a disruption of confidentiality, integrity, and availability of protected information.Recommendations
For net-snmp versions 5.1.2 through 5.3.1, update to version 5.4.2.1 or later.
For net-snmp-devel versions 5.1.2 through 5.3.1, update to version 5.4.2.1 or later.
For net-snmp-libs versions 5.1.2 through 5.3.1, update to version 5.4.2.1 or later.
For net-snmp-utils versions 5.1.2 through 5.3.1, update to version 5.4.2.1 or later.
As a temporary workaround, consider restricting access to the SNMP service until a patch is available.
