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 •

A memory leak in glibc 2.1.1 (released on May 24, 1999) can be reached and amplified through the LD_HWCAP_MASK environment variable. Please note that many versions of glibc are not vulnerable to this issue if patched for CVE-2017-1000366. Una fuga de memoria en glibc 2.1.1 (publicado el 24 de mayo de 1999) puede ser alcanzada y amplificada mediante la variable de entorno LD_HWCAP_MASK. 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 http://www.openwall.com/lists/oss-security/2019/06/27/7 http://www.openwall.com/lists/oss-security/2019/06/28/1 http://www.openwall.com/lists/oss-security/2019/06/28/2 https://security.netapp.com/advisory/ntap-20190404-0003 • CWE-772: Missing Release of Resource after Effective Lifetime •

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 •

The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation. La herramienta de resolución de zonas stub de DNS en la librería GNU C, también conocida como glibc o libc6, en sus versiones anteriores a la 2.26 cuando el soporte EDNS está activado, solicitará respuestas UDP de gran tamaño de servidores de nombres, pudiendo simplificar los ataques de suplantación de DNS debido a una fragmentación de IP. • http://www.securityfocus.com/bid/100598 https://access.redhat.com/errata/RHSA-2018:0805 https://arxiv.org/pdf/1205.4011.pdf https://sourceware.org/bugzilla/show_bug.cgi?id=21361 https://access.redhat.com/security/cve/CVE-2017-12132 https://bugzilla.redhat.com/show_bug.cgi?id=1477529 • CWE-770: Allocation of Resources Without Limits or Throttling •
