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 •
CVSS: 9.8EPSS: 0%CPEs: 20EXPL: 0CVE-2018-6485 – glibc: Integer overflow in posix_memalign in memalign functions
https://notcve.org/view.php?id=CVE-2018-6485
An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption. Un desbordamiento de enteros en la implementación de posix_memalign en las funciones memalign en GNU C Library (también conocido como glibc o libc6) en versiones 2.26 y anteriores podría provocar que estas funciones devuelvan un puntero a un área de la memoria dinámica (heap) demasiado pequeña, pudiendo corromper el heap. • http://bugs.debian.org/878159 http://www.securityfocus.com/bid/102912 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190404-0003 https://sourceware.org/bugzilla/show_bug.cgi?id=22343 https://usn.ubuntu.com/4218-1 https://usn.ubuntu.com/4416-1 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html https://access.redhat.com/security/cve/CVE-2018-6485 https:/ • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
