https://notcve.org/view.php?id=CVE-2019-6488
The string component in the GNU C Library (aka glibc or libc6) through 2.28, when running on the x32 architecture, incorrectly attempts to use a 64-bit register for size_t in assembly codes, which can lead to a segmentation fault or possibly unspecified other impact, as demonstrated by a crash in __memmove_avx_unaligned_erms in sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy. El componente string en GNU C Library (también conocido como glibc o libc6) hasta la versión 2.28, cuando se ejecuta en la arquitectura x32, intenta usar de manera incorrecta un registro de 64 bits para "size_t" en códigos de ensamblado, lo que puede provocar un fallo de segmentación u otro impacto no especificado, tal y como queda demostrado con un cierre inesperado en __memmove_avx_unaligned_ermsen sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S durante un memcpy. • http://www.securityfocus.com/bid/106671 https://security.gentoo.org/glsa/202006-04 https://sourceware.org/bugzilla/show_bug.cgi?id=24097 • CWE-404: Improper Resource Shutdown or Release •

https://notcve.org/view.php?id=CVE-2018-19591
In the GNU C Library (aka glibc or libc6) through 2.28, attempting to resolve a crafted hostname via getaddrinfo() leads to the allocation of a socket descriptor that is not closed. This is related to the if_nametoindex() function. En la biblioteca GNU C (también conocida como glibc o libc6) hasta la versión 2.28, los intentos para resolver un nombre de host manipulado mediante getaddrinfo() conducen a la asignación de un descriptor de un socket que no está cerrado. Esto está relacionado con la función if_nametoindex(). • http://www.securityfocus.com/bid/106037 http://www.securitytracker.com/id/1042174 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BO7WHN52GFMC5F2I2232GFIPSSXWFV7G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M52KE4YR3GNMHQUOS3DKAGZD5TQ5D5UH https://security.gentoo.org/glsa/201903-09 https://security.gentoo.org/glsa/201908-06 https://security.netapp.com/advisory/ntap-20190321-0003 https://sourceware.org/bugzilla/show_bug.cgi?i • CWE-20: Improper Input Validation •
CVSS: 9.8EPSS: 1%CPEs: 12EXPL: 0CVE-2018-11236 – glibc: Integer overflow in stdlib/canonicalize.c on 32-bit architectures leading to stack-based buffer overflow
https://notcve.org/view.php?id=CVE-2018-11236
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 un desbordamiento de enteros en arquitecturas de 32 bits. Esto podría desembocar en un desbordamiento de búfer basado en pila y en una potencial ejecución de código arbitrario. • http://www.securityfocus.com/bid/104255 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190329-0001 https://security.netapp.com/advisory/ntap-20190401-0001 https://sourceware.org/bugzilla/show_bug.cgi?id=22786 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Bh=5460617d1567657621107d895ee2dd83bc1f88f2 https://usn.ubuntu.com/4416-1 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.h • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-11237
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. A buffer overflow has been discovered in the GNU C Library (aka glibc or libc6) in the __mempcpy_avx512_no_vzeroupper function when particular conditions are met. An attacker could use this vulnerability to cause a denial of service or potentially execute code. GNU glibc versions prior to 2.27 suffer from a buffer overflow vulnerability. • http://www.securityfocus.com/bid/104256 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190329-0001 https://security.netapp.com/advisory/ntap-20190401-0001 https://sourceware.org/bugzilla/show_bug.cgi?id=23196 https://usn.ubuntu.com/4416-1 https://www.exploit-db.com/exploits/44750 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html https://access.redhat.com/security • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
