LowCVSS 1.9 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 7/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.36% (FIRST EPSS).
  • Fixed version: kernel (Red Hat:enterprise_linux:5::server) 0:2.6.18-348.1.1.el5; kernel-debug (Red Hat:enterprise_linux:5::server) 0:2.6.18-348.1.1.el5; kernel-debug-debuginfo (Red Hat:enterprise_linux:5::server) 0:2.6.18-348.1.1.el5.

Low priority for now. Upgrade to kernel (Red Hat:enterprise_linux:5::server) 0:2.6.18-348.1.1.el5; kernel-debug (Red Hat:enterprise_linux:5::server) 0:2.6.18-348.1.1.el5; kernel-debug-debuginfo (Red Hat:enterprise_linux:5::server) 0:2.6.18-348.1.1.el5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The ExecShield feature in a certain Red Hat patch for the Linux kernel in Red Hat Enterprise Linux (RHEL) 5 and 6 and Fedora 15 and 16 does not properly handle use of many shared libraries by a 32-bit executable file, which makes it easier for context-dependent attackers to bypass the ASLR protection mechanism by leveraging a predictable base address for one of these libraries.
