CVE-2020-10878: Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation.

HighCVSS 8.6 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 4.8% (FIRST EPSS); higher than 92.1% 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.
  • Fixed version: perl (Alpine:v3.10) 5.28.3-r0; perl (Alpine:v3.11) 5.30.3-r0; perl (Alpine:v3.9) 5.26.3-r1.
  • Mentioned 3 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to perl (Alpine:v3.10) 5.28.3-r0; perl (Alpine:v3.11) 5.30.3-r0; perl (Alpine:v3.9) 5.26.3-r1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.
