18 May 2018 — An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in __mempcpy_avx512_no_vzeroupper. Una implementación optimizada para AVX-512 de la función mempcpy en GNU C Library (también conocido como glibc o libc6), en versiones 2.27 y anteriores, podría escribir datos más allá del búfer objetivo, lo que desemboca en un desbordamiento de búfer en __mempcpy_avx512_no_vzeroupper.

18 May 2018 — stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution. stdlib/canonicalize.c en GNU C Library (también conocida como glibc o libc6), en versiones 2.27 y anteriores, al procesar argumentos con un nombre de ruta muy largo en la función realpath, podría encontrarse con u... • http://www.securityfocus.com/bid/104255 • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

05 Dec 2017 — The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cache (aka tcache) feature enables a code path that lacks an integer overflow check.
