Detailsinfo

A vulnerability was found in GNU binutils 2.28 (Programming Tool Software) and classified as critical. Affected by this issue is the function score_opcodes of the file opcodes/score7-dis.c. The manipulation as part of a Binary File leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The score_opcodes function in opcodes/score7-dis.c 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 during "objdump -D" execution.
