VAR-201812-0951

Vulnerability from variot - Updated: 2023-12-18 11:39

The _bfd_generic_read_minisymbols function in syms.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31, has a memory leak via a crafted ELF file, leading to a denial of service (memory consumption), as demonstrated by nm. GNU Binutils Contains a resource management vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. GNU Binutils is prone to a denial-of-service vulnerability. Attackers can exploit this issue to cause denial-of-service condition, denying service to legitimate users. GNU Binutils 2.31 is vulnerable; other versions may also be affected.

Severity: Normal Title: Binutils: Multiple vulnerabilities Date: August 03, 2019 Bugs: #672904, #672910, #674668, #682698, #682702 ID: 201908-01


Synopsis

Multiple vulnerabilities have been found in Binutils, the worst of which may allow remote attackers to cause a Denial of Service condition.

Background

The GNU Binutils are a collection of tools to create, modify and analyse binary files. Many of the files use BFD, the Binary File Descriptor library, to do low-level manipulation. Please review the referenced CVE identifiers for details.

Impact

A remote attacker, by enticing a user to compile/execute a specially crafted ELF, object, PE, or binary file, could possibly cause a Denial of Service condition or have other unspecified impacts.

Workaround

There is no known workaround at this time.

Resolution

All Binutils users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=sys-devel/binutils-2.32-r1"
