RHEL 7 : devtoolset-12-binutils (RHSA-2023:3269)

medium Nessus Plugin ID 176321

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:3269 advisory.

- Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol.
(CVE-2021-3826)

- An illegal memory access flaw was found in the binutils package. Parsing an ELF file containing corrupt symbol version information may result in a denial of service. This issue is the result of an incomplete fix for CVE-2020-16599. (CVE-2022-4285)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected devtoolset-12-binutils and / or devtoolset-12-binutils-devel packages.
