Summary
A flaw was found in binutils. The `copy_section` function in `binutils/objcopy.c` is susceptible to a heap-based buffer overflow due to improper bounds checking during data copying. This flaw allows a local attacker to provide a specially crafted file. This manipulation can lead to a denial of service.
Remediation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

01

What, why and how

A vulnerability classified as problematic was found in GNU Binutils 2.45. Affected by this vulnerability is the function copy_section of the file binutils/objcopy.c. The manipulation leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The patch is named 08c3cbe5926e4d355b5cb70bbec2b1eeb40c2944. It is recommended to apply a patch to fix this issue.

A vulnerability classified as problematic was found in GNU Binutils 2.45. Affected by this vulnerability is the function copy_section of the file binutils/objcopy.c. The manipulation leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The patch is named 08c3cbe5926e4d355b5cb70bbec2b1eeb40c2944. It is recommended to apply a patch to fix this issue.

Why

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.
