CVSS: 6.0EPSS: 0%CPEs: 13EXPL: 0CVE-2020-14310 – grub2: Integer overflow read_section_as_string may lead to heap-based buffer overflow
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 •

hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555. El archivo hw/net/xgmac.c en el controlador Ethernet XGMAC en QEMU antes del 20/07/2020, presenta un desbordamiento de búfer. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00024.html http://www.openwall.com/lists/oss-security/2020/07/22/1 https://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=5519724a13664b43e225ca05351c60b4468e4555 https://lists.nongnu.org/archive/html/qemu-devel/2020-07/msg03497.html https://lists.nongnu.org/archive/html/qemu-devel/2020-07/msg05745.html https://security.gentoo.org/glsa/202208-27 https://usn.ubuntu.com/4467-1 https://www.debian.org/security/2020/dsa-47 • CWE-787: Out-of-bounds Write •
