[Bug libc/23323] Recommendations for devs stuck with old glibc versions

[amb]

Hi,

I am forced to build against an old glibc version in order to run my
code on a large number of target linux systems. For developers like
me, what is the recommended way to mitigate the issue described in
https://sourceware.org/bugzilla/show_bug.cgi?id=23323 ?

If mitigation is not possible, should I be concerned about this as a
potential security issue for my application? I don't know if this
issue was ever assigned a CVE so I was not able to query its severity.
Is there a CVE for this?

Thanks
