Net-SNMP 5.7.3-Next?

Team,

Apologies up front if this is not the correct place to raise a question like this, feel free to redirect me.

Back in 2015 a defect (2615) was created against NetSNMP that reported a security issue (CVE-2015-5621).

Later on, 22 Jun 2015, another defect was reported (2643).

Here's the link:

https://sourceforge.net/p/net-snmp/bugs/2643/

When I read 2643, it tells me that its a duplicate of 2615.

I am not able to get at defect 2615 - it seems to be hidden/removed.....I can see defects 2614 & 2616, but not 2615.

Anyhow, when I read through defect 2643, the reporter tells us that they are confirming a security defect known as CVE-2015-5621 is present in Net-SNMP 5.7.3. The defect is reported against the snmp_pdu_parse().

Shortly afterwards, the Net-SNMP team respond to defect 2643, confirming:

- its a duplicate defect (of 2615)

- its fixed

- its not released yet (that was 26 Jun 2015)

I also know that Net-SNMP 5.7.3 was first released in Dec 2014, so I am sort of hoping there will be some sort of a maintenance release that contains a fix for the reported security issue and maybe a roll up of other patches.

Does anyone have any news/insights on prospects of a patched 5.7.3? and if so when?

I've also discovered a possible fix for the issue, but I cannot tell if this fix is applicable to the 5.7.3 code I have (it looks similar, but the line numbers are a bit different in my version compared to what's published here).

Maybe someone can tell me if this changed code (snmplib/snmp_api.c) (which was supposed to address the issue):

https://sourceforge.net/p/net-snmp/code/ci/f23bcd3ac6ddee5d0a48f9703007ccc738914791/

Is all that's needed?

Is this fix cross-dependent on other fixes elsewhere?

Regards,

Bb
