+Version 2.28.1

+

+Deprecated and removed features, and other changes affecting compatibility:

+

+* For powercp64le ABI, Transactional Lock Elision is now enabled iff kernel

+ indicates that it will abort the transaction prior to entering the kernel

+ (PPC_FEATURE2_HTM_NOSC on hwcap2). On older kernels the transaction is

+ suspended, and this caused some undefined side-effects issues by aborting

+ transactions manually. Glibc avoided it by abort transactions manually on

+ each syscall, but it lead to performance issues on newer kernels where the

+ HTM state is saved and restore lazily (the state being saved even when the

+ process actually does not use HTM).

+

+The following bugs are resolved with this release:

+

+ [19444] build failures with -O1 due to -Wmaybe-uninitialized

+ [20018] getaddrinfo should reject IP addresses with trailing characters

+ [20209] localedata: Spelling mistake for Sunday in Greenlandic kl_GL

+ [22927] libanl: properly cleanup if first helper thread creation failed

+ [23400] stdlib/test-bz22786.c creates temporary files in glibc source tree

+ [23497] readdir64@GLIBC_2.1 cannot parse the kernel directory stream

+ [23509] CET enabled glibc is incompatible with the older linker

+ [23521] nss_files aliases database file stream leak

+ [23538] pthread_cond_broadcast: Fix waiters-after-spinning case

+ [23562] signal: Use correct type for si_band in siginfo_t

+ [23578] regex: Fix memory overread in re_compile_pattern

+ [23579] libc: Errors misreported in preadv2

+ [23606] Missing ENDBR32 in sysdeps/i386/start.S

+ [23614] powerpc: missing CFI register information in __mpn_* functions

+ [23679] gethostid: Missing NULL check for gethostbyname_r result

+ [23709] Fix CPU string flags for Haswell-type CPUs

+ [23717] Fix stack overflow in stdlib/tst-setcontext9

+ [23821] si_band in siginfo_t has wrong type long int on sparc64

+ [23822] ia64 static libm.a is missing exp2f, log2f and powf symbols

+ [23864] libc: [riscv] missing kernel-features.h undefines

+ [23844] pthread_rwlock_trywrlock results in hang

+ [23927] Linux if_nametoindex() does not close descriptor (CVE-2018-19591)

+ [23972] __old_getdents64 uses wrong d_off value on overflow

+ [24018] gettext may return NULL

+ [24022] riscv may lack <asm/syscalls.h>

+ [24024] strerror() might set errno to ENOMEM due to -fno-math-error

+ [24027] malloc: Integer overflow in realloc

+ [24034] tst-cancel21-static fails with SIGBUS on pre-ARMv7 when using GCC 8

+ [24040] riscv64: unterminated call chain in __thread_start

+ [24097] Can't use 64-bit register for size_t in assembly codes for x32 (CVE-2019-6488)

+ [24155] x32 memcmp can treat positive length as 0 (if sign bit in RDX is set) (CVE-2019-7309)

+ [24161] __run_fork_handlers self-deadlocks in malloc/tst-mallocfork2

+

+Security related changes:

+

+ CVE-2018-19591: A file descriptor leak in if_nametoindex can lead to a

+ denial of service due to resource exhaustion when processing getaddrinfo

+ calls with crafted host names. Reported by Guido Vranken.

+

+ CVE-2019-6488: On x32, the size_t parameter may be passed in the lower

+ 32 bits of a 64-bit register with with non-zero upper 32 bit. When it

+ happened, accessing the 32-bit size_t value as the full 64-bit register

+ in the assembly string/memory functions would cause a buffer overflow.

+ Reported by H.J. Lu.

+

+ CVE-2019-7309: x86-64 memcmp used signed Jcc instructions to check

+ size. For x86-64, memcmp on an object size larger than SSIZE_MAX

+ has undefined behavior. On x32, the size_t argument may be passed

+ in the lower 32 bits of the 64-bit RDX register with non-zero upper

+ 32 bits. When it happened with the sign bit of RDX register set,

+ memcmp gave the wrong result since it treated the size argument as

+ zero. Reported by H.J. Lu.

+

+ CVE-2016-10739: The getaddrinfo function could successfully parse IPv4

+ addresses with arbitrary trailing characters, potentially leading to data

+ or command injection issues in applications.

+

+ CVE-2019-9169: Attempted case-insensitive regular-expression match

+ via proceed_next_node in posix/regexec.c leads to heap-based buffer

+ over-read. Reported by Hongxu Chen.
