CVE-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 •

A buffer overflow in glibc 2.5 (released on September 29, 2006) and can be triggered through the LD_LIBRARY_PATH environment variable. Please note that many versions of glibc are not vulnerable to this issue if patched for CVE-2017-1000366. Un desbordamiento de búfer en glibc 2.5 (publicado el 29 de septiembre de 2006) puede ser desencadenado mediante la variable de entorno LD_LIBRARY_PATH. Hay que tener en cuenta que muchas versiones de glibc no son vulnerables a este problema si se corrigen con el parche para CVE-2017-1000366. • https://www.exploit-db.com/exploits/43331 http://seclists.org/oss-sec/2017/q4/385 https://security.netapp.com/advisory/ntap-20190404-0003 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

scanf and related functions in glibc before 2.15 allow local users to cause a denial of service (segmentation fault) via a large string of 0s. La función scanf y las funciones relacionadas en glibc en versiones anteriores a la 2.15 permiten que usuarios locales provoquen una denegación de servicio (fallo de segmentación) mediante una larga cadena de ceros. • http://www.openwall.com/lists/oss-security/2015/03/12/14 https://bugzilla.redhat.com/show_bug.cgi?id=1196745 https://marc.info/?l=gimp-developer&m=129567990905823&w=2 https://sourceware.org/bugzilla/show_bug.cgi?id=13138#c4 https://sourceware.org/git/?p=glibc.git%3Ba=commitdiff%3Bh=20b38e0 https://sourceware.org/git/? • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Use-after-free vulnerability in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library (aka glibc or libc6) before 2.26 allows remote attackers to have unspecified impact via vectors related to error path. Vulnerabilidad de uso de memoria previamente liberada en la función clntudp_call en sunrpc/clnt_udp.c en GNU C Library (también conocida como glibc o libc6), en versiones anteriores a la 2.26, permite que atacantes remotos provoquen un impacto sin especificar mediante vectores relacionados con una ruta de error. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SYZL6PAKI73XYRJYL5VLDGA4FFGWMB7A https://sourceware.org/bugzilla/show_bug.cgi?id=21115 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Bh=d42eed4a044e5e10dfb885cf9891c2518a72a491 https://usn.ubuntu.com/4416-1 https://www.securityfocus.com/bid/100679 • CWE-416: Use After Free •
