AlienVault OTX Malware

This update includes the following RPMs:

busybox:
  * busybox-1.37.0-7.2.hum1 (aarch64, x86_64)
  * busybox-petitboot-1.37.0-7.2.hum1 (aarch64, x86_64)
  * busybox-shared-1.37.0-7.2.hum1 (aarch64, x86_64)
  * busybox-1.37.0-7.2.hum1.src (src)

Security Fix(es):

busybox:
  * CVE-2026-26157
  * CVE-2026-26158

The vulnerability CVE-2026-26157 in BusyBox arises from incomplete path sanitization in its archive extraction utilities. This flaw allows attackers to craft malicious archives that, when extracted under certain conditions, can write files outside the intended extraction directory. This arbitrary file overwrite can lead to modification of sensitive system files and potentially enable code execution. The issue affects BusyBox packages included in Red Hat Hardened Images RPMs for aarch64 and x86_64 architectures. Red Hat has published an advisory (RHSA-2026:13831) detailing the issue and recommending mitigation steps. The CVSS v3.1 score assigned by Red Hat is 7.0 (High), with attack vector local, high attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability. The advisory does not explicitly state a fixed version or patch availability but provides updated RPM versions (busybox-1.37.0-7.2.hum1).

Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update

A flaw was found in BusyBox. Incomplete path sanitization in its archive extraction utilities allows an attacker to craft malicious archives that when extracted, and under specific conditions, may write to files outside the intended directory. This can lead to arbitrary file overwrite, potentially enabling code execution through the modification of sensitive system files.

CVE-2026-26157 is a vulnerability in BusyBox's archive extraction utilities included in Red Hat Hardened Images. The issue arises from incomplete path sanitization, allowing attackers to craft malicious archives that, when extracted under specific conditions, can write files outside the intended extraction directory. This can lead to arbitrary file overwrite, which may enable code execution by altering sensitive system files. Red Hat has issued a security advisory (RHSA-2026:13831) providing updated BusyBox RPMs (version 1.37.0-7.2.hum1) that fix this vulnerability. The CVSS 3.1 vector indicates the attack requires local access with high complexity, no privileges, and user interaction, but can result in high confidentiality, integrity, and availability impacts.
