NULL Dereference in Certificate Verification with OCSP Checking

Multiple security vulnerabilities affect the litellm-database package. These issues are resolved in later releases. See references for individual vulnerability details.

OpenSSL contained multiple vulnerabilities including a heap buffer over-read in ASN.1 parsing (CVE-2026-34180), acceptance of forged CMS AuthEnvelopedData messages (CVE-2026-34182), NULL pointer dereferences causing crashes (e.g., CVE-2026-42764, CVE-2026-42766, CVE-2026-42767), unbounded memory growth in QUIC handling (CVE-2026-34183), and cryptographic bypasses such as ignoring IV in AES-OCB mode (CVE-2026-42770) and incorrect tag processing in AES-GCM-SIV and AES-SIV modes (CVE-2026-45446). Some vulnerabilities could lead to denial of service or information disclosure, and others could allow bypassing integrity or authentication checks. These issues were fixed in updated OpenSSL packages provided by Ubuntu for multiple LTS releases and other distributions. The vendor advisory confirms the availability of patches and recommends updating to the specified package versions.
