Fix for net-snmp vulnerability CVE-2015-5621

Post by tsrini » 2020/03/04 06:49:43

Hi Team,

Is there any fix available in CentOS 7.6 updates (or) in later versions of CentOS for the net-snmp vulnerability - CVE-2015-5621 ?

I have checked all the change logs of available RPMs from CentOS 7 to 8 but couldn't see any fix related to this vulnerability. Even I couldn't see anything in change log of net-snmp website as well.

Thanks,
Srini

https://access.redhat.com/security/cve/CVE-2015-5621

Fixed in net-snmp-5.7.2-20.el7_1.1.x86_64.rpm
CentOS 6 will die in November 2020 - migrate sooner rather than later!
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 is dead, do not use it.

Thanks TrevoH.

Is this fix ported in CentOS's net-snmp package?

We are using Centos 7.6 which uses net-snmp-5.7.2-37.el7.x86_64 and our internal Security Team reported this version is vulnerable to the CVE.

Is the fix in Redhat version net-snmp-5.7.2-20.el7_1.1.x86_64.rpm available in any of the below CentOS's packages,

CentOS 7.6 update: net-snmp-5.7.2-38.el7_6.2.x86_64.rpm
CentOS 7.7 net-snmp-5.7.2-43.el7.src.rpm
CentOS 8.0 net-snmp-5.8-7.el8_0.2.src.rpm
CentOS 8.1 net-snmp-5.8-12.el8_1.src.rpm

The fix will be in all higher versions than the one it says the fix is in.

Hi TrevoH,

As per our Security Team, the CentOS 7.6 version net-snmp-5.7.2-37.el7.x86_64 (which is even higher than the RHEL fix version net-snmp-5.7.2-20.el7_1.1.x86_64.rpm) is vulnerable.

Thats why little confused on the fix version which we need to pick for CentOS.

Regards,
Srini

Your security team is probably looking at just the banner reported by snmp which most likely just contains the major version 5.7.2. This is very common with vulnerability scanners and can be ignored.
