The vulnerability of the read_section function in the dwarf2.c component of the GNU Binutils development environment allows a hacker to induce a service failure.

The vulnerability of the readsection function in the dwarf2.c component of the GNU Binutils development environment relates to reading data beyond the allowed buffer limits. Exploiting this vulnerability allows an attacker to cause a service failure by using a specially created ELF file...

The vulnerability of the read_section() function in the dwarf2.c component of the GNU Binutils development environment allows a hacker to induce a service failure.

The vulnerability of the readsection function in the dwarf2.c component of the GNU Binutils development environment is related to insufficient input data validation. Exploiting this vulnerability allows an attacker who operates remotely to trigger a service failure using a specially created file...

CLSA-2021-1633442827 Fix of CVE: CVE-2021-3487

CVE-2021-3487: excessive debug section size can cause excessive memory consumption in bfd's dwarf2.c readsection...

The vulnerability in the implementation of the read_section_as_string() function of the Grub2 operating system allows a attacker to influence data integrity or cause service failures.

The vulnerability of the readsectionasstring function in the Grub2 operating system’s loader is related to the issue of data operations going beyond the buffer boundaries. This is because the maximum length of a UINT32MAX is 1 byte. Exploiting this vulnerability could allow an attacker to influen...

grub2: Integer overflow read_section_as_string may lead to heap-based buffer overflow

A flaw was found in grub2. An expected font value is not verified before proceeding with buffer allocations allowing an attacker to use a malicious font file to create an arithmetic overflow, zero-sized allocation, and further heap-based buffer overflow. The highest threat from this vulnerability...

grub2 heap buffer overflow vulnerability (CNVD-2020-45111)

GRUB2 is a bootloader. A heap buffer overflow vulnerability exists in the readsectionasstring function in grub2 versions prior to 2.06. An attacker can exploit this vulnerability to cause an arithmetic overflow and zero-size allocation via a malicious font file with the name UINT32MAX, which can...

ALPINE-CVE-2020-14310

There is an issue on grub2 before version 2.06 at function readsectionasstring. It expects a font name to be at max UINT32MAX - 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...
