Multiple vulnerabilities have been found in elfutils, the worst of which may allow remote attackers to cause a Denial of Service condition.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/elfutils | * | < 0.169-r1 | >= 0.169-r1 |
Elfutils provides a library and utilities to access, modify and analyse ELF objects.
Multiple vulnerabilities have been discovered in elfutils. Please review the referenced CVE identifiers for details.
A remote attacker could possibly cause a Denial of Service condition via specially crafted ELF files.
There is no known workaround at this time.
All elfutils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/elfutils-0.169-r1"
Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
A heap-based buffer overflow vulnerability in elfutils might allow remote attackers to execute arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/elfutils | * | < 0.159 | >= 0.159 |
Elfutils provides a library and utilities to access, modify and analyse ELF objects.
An integer overflow, in the check_section function of dwarf_begin_elf.c, in the libdw library can lead to a heap-based buffer overflow.
A remote attacker could entice a user to open a specially crafted file, possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All elfutils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/elfutils-0.159"
Various utilities from the GNU Binutils and elfutils packages are vulnerable to a heap based buffer overflow, potentially resulting in the execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/elfutils | * | < 0.108 | >= 0.108 |
| sys-devel/binutils | * | < 2.16-r1 | >= 2.14.90.0.8-r3 (revision), >= 2.15.90.0.1.1-r5 (revision), >= 2.15.90.0.3-r5 (revision), >= 2.15.91.0.2-r2 (revision), >= 2.15.92.0.2-r10 (revision), >= 2.16-r1 |
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. Elfutils provides a library and utilities to access, modify and analyse ELF objects.
Tavis Ormandy and Ned Ludd of the Gentoo Linux Security Audit Team discovered an integer overflow in the BFD library and elfutils, resulting in a heap based buffer overflow.
Successful exploitation would require a user to access a specially crafted binary file, resulting in the execution of arbitrary code.
There is no known workaround at this time.
All GNU Binutils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose sys-devel/binutils
All elfutils users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/elfutils-0.108"
