Detailsinfo

A vulnerability was found in GNU binutils 2.28 (Programming Tool Software). It has been classified as critical. Affected is an unknown code block of the file bfd/vms-alpha.c of the component libbfd. The manipulation as part of a Binary File leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

bfd/vms-alpha.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted binary file, as demonstrated by mishandling of this file in the _bfd_vms_get_value and _bfd_vms_slurp_etir functions during "objdump -D" execution.
