bug#70581: PHP, glibc, and CVE-2024-2961

[McSinyx]

Hello Guix,

Last week, an overflow bug in glibc's iconv(3) was discovered:
https://www.openwall.com/lists/oss-security/2024/04/17/9

It may enable remove code execution through PHP.  Due to
the immutable nature of Guix, is it possible to hotpatch
this using graft, or do we need to rebuild to world?

Kind regards,
