CriticalCVSS 9.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 1.5% (FIRST EPSS); higher than 74.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: azl3 glib 2.78.1-5 on Azure Linux 3.0 2.78.1-5; azl3 glib 2.78.6-1 on Azure Linux 3.0 2.78.1-5; cbl2 glib 2.71.0-3 on CBL Mariner 2.0 2.71.0-3.

Low priority for now. Upgrade to azl3 glib 2.78.1-5 on Azure Linux 3.0 2.78.1-5; azl3 glib 2.78.6-1 on Azure Linux 3.0 2.78.1-5; cbl2 glib 2.71.0-3 on CBL Mariner 2.0 2.71.0-3 or later.

Weakness class (CWE)

CWE-120 · Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

CVSS vector

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

nvd-secondary

Root cause

When data is copied, the source length is not compared with the size of the destination buffer. Excess data overwrites adjacent memory.
