Noroxi assessment

Priority: Plan (action score 43/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 44% (FIRST EPSS); higher than 98.7% 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.
  • Fixed version: openssl (Debian:12) 1.0.2e-1; openssl (Debian:7) 1.0.1e-2+deb7u18; openssl (Debian:8) 1.0.1k-3+deb8u2.

Add it to your regular patch cycle. Upgrade to openssl (Debian:12) 1.0.2e-1; openssl (Debian:7) 1.0.1e-2+deb7u18; openssl (Debian:8) 1.0.1k-3+deb8u2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

crypto/rsa/rsa_ameth.c in OpenSSL 1.0.1 before 1.0.1q and 1.0.2 before 1.0.2e allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an RSA PSS ASN.1 signature that lacks a mask generation function parameter.
