February 14, 2025 - 1.20.3 came before the broken glibc, so it just couldn't. There's an an issue opened on GitHub, so devs are aware of this and probably will fix it in the next update/patch.

Recently, Google experts have revealed a security fault because of which many devices and apps are at risk – Linux servers are also a part of it. It is a bug known as glibc bug which can distress hundreds of devices, applications and softwares which are internet connected.

This issue has been rated as having Critical impact by Red Hat Product Security. In a default libresolv configuration, the UDP-based vector is mitigated by using a trusted, protocol-compliant DNS resolver on a trusted network. A compliant resolver will not produce the kind of oversized responses which are necessary to exploit this vulnerability because by default, the glibc resolver does not enable EDNS0 and does not request large responses.

August 20, 2025 - Our engineers were able to obtain a stack trace of the crash, but unfortunately, it did not provide much information about what was going on. We decided to revert the introduction of the hardened flags when compiling glibc until we could fully understand the issue.

Security reports that should not be made immediately public can be sent directly to the maintainers. If there is no response to an urgent issue, you can escalate ...

April 16, 2025 - "The most vulnerable devices to this glibc vulnerability are IoT devices due to their extensive use of the Linux kernel within custom operating systems," explained John Gallagher, vice president of Viakoo Labs at ... "Not only will different IoT device manufacturers have different schedules for producing patches, but there will be a lengthy process to ensure that all devices are remediated." The Qualys TRU disclosed the issue to Linux package maintainers on September 4 and sent a patch on September 19th.

April 23, 2024 - The glibc Bug Unveiled A recent revelation by security researcher Charles Fol has brought to light a critical vulnerability within glibc, a cornerstone of the Linux operating system. This bug, which has existed unnoticed for over two decades, now poses a significant threat to PHP web applications.

August 16, 2021 - When a fix was made in early June for a relatively minor problem, CVE-2021-33574, which could result in application crashes, this was a good thing. Unfortunately, it turned out the fix introduced a new and nastier problem, CVE-2021-38604.

April 3, 2025 - glibc actually goes to a fair bit of effort to be compatible with old binaries unlike most of the rest of the Linux userspace. The binaries I built for my side project back in 2015 (BlastEm 0.3.0) still work fine on modern Linux and they dynamically link against glibc.

Even though glibc 2.35 to glibc 2.37 added a lot of internal refactoring, it still does not support building with a compiler other than GCC. The glibc and all of the tests can be built with LLVM LLD; and, although it is not constantly tested, there is no known issue using it for 32 and 64 bits ARM and x86.
