https://notcve.org/view.php?id=CVE-2020-14311
There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. Se presenta un problema con grub2 versiones anteriores a 2.06, mientras se maneja un symlink en los sistemas de archivos ext. Un sistema de archivos que contiene un enlace simbólico con un tamaño de inode de UINT32_MAX causa un desbordamiento aritmético conllevando a una asignación de memoria de tamaño cero con el posterior desbordamiento del búfer en la región heap de la memoria A flaw was found in grub2 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow, leading to a zero-sized memory allocation with a subsequent heap-based buffer overflow. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00017.html http://www.openwall.com/lists/oss-security/2021/09/17/2 http://www.openwall.com/lists/oss-security/2021/09/17/4 http://www.openwall.com/lists/oss-security/2021/09/21/1 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-14311 https://security.gentoo.org/glsa/202104-05 https://usn.ubuntu.com/4432-1 https://acce • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2020-14310
There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. Se presenta un problema en grub2 versiones anteriores a 2.06, en la función read_section_as_string(). Se espera que el nombre de la fuente sea una longitud máxima UINT32_MAX - 1 en bytes, pero no lo verifica antes de proceder con la asignación del búfer para leer el valor desde el valor de la fuente. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00017.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-14310 https://security.gentoo.org/glsa/202104-05 https://usn.ubuntu.com/4432-1 https://access.redhat.com/security/cve/CVE-2020-14310 https://bugzilla.redhat.com/show_bug.cgi?id=1852030 • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
