CVE-2019-3813· NVD / CVE Program· CNA redhat

Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt.

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 1.2% (FIRST EPSS); higher than 67.7% of all records.
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: spice (Alpine:v3.10) 0.14.1-r4; spice (Alpine:v3.6) 0.13.3-r4; spice (Alpine:v3.7) 0.14.1-r2.

Low priority for now. Upgrade to spice (Alpine:v3.10) 0.14.1-r4; spice (Alpine:v3.6) 0.13.3-r4; spice (Alpine:v3.7) 0.14.1-r2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers.
