The GNU C Library ================= The GNU C Library version 2.37 is now available.
The GNU C Library is used as *the* C library in the GNU system and in GNU/Linux systems, as well as many other systems that use Linux as the kernel. The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C11 and POSIX.1-2017. It is also internationalized and has one of the most complete internationalization interfaces known. The GNU C Library webpage is at http://www.gnu.org/software/libc/ Packages for the 2.37 release may be downloaded from: http://ftpmirror.gnu.org/libc/ http://ftp.gnu.org/gnu/libc/ The mirror list is at http://www.gnu.org/order/ftp.html Distributions are encouraged to track the release/* branches corresponding to the releases they are using. The release branches will be updated with conservative bug fixes and new features while retaining backwards compatibility. NEWS for version 2.37 ===================== Major new features: * The getent tool now supports the --no-addrconfig option. The output of getent with --no-addrconfig may contain addresses of families not configured on the current host i.e. as-if you had not passed AI_ADDRCONFIG to getaddrinfo calls. Deprecated and removed features, and other changes affecting compatibility: * The dynamic linker no longer loads shared objects from the "tls" subdirectories on the library search path or the subdirectory that corresponds to the AT_PLATFORM system name, or employs the legacy AT_HWCAP search mechanism, which was deprecated in version 2.33. Security related changes: CVE-2022-39046: When the syslog function is passed a crafted input string larger than 1024 bytes, it reads uninitialized memory from the heap and prints it to the target log file, potentially revealing a portion of the contents of the heap.
