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 •
CVSS: 7.8EPSS: 0%CPEs: 15EXPL: 1CVE-2018-11237 – glibc: Buffer overflow in __mempcpy_avx512_no_vzeroupper
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 •

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 •
