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...

An issue was discovered in GNU Binutils 2.32. It is a heap-based buffer overflow in process_mips_specific in readelf.c via a malformed MIPS option section.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd) as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character.

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...
