CVE-2015-0292: Integer underflow in the EVP_DecodeUpdate function in crypto/evp/encode.c in the base64-decoding implementa...

Security readout for executives and security teams

A bug in OpenSSL's base64 decoder can let remote input crash software or corrupt memory. Because OpenSSL is widely embedded, exposure depends on where vulnerable versions are used and whether they decode untrusted base64. Treat it as an availability risk with uncertain secondary impact. Likely exposure is software, servers, appliances, or vendor products using vulnerable OpenSSL builds and decoding attacker-controlled base64 data. The source bundle lists multiple downstream vendor advisories, but does not prove any specific organization, product instance, or internet-facing service is affected. Schedule remediation through normal vulnerability management, with faster handling for internet-facing or high-availability services. The available evidence supports real crash and memory-corruption risk, but not confirmed active exploitation from the provided sources. Mitigation focus: Upgrade OpenSSL to fixed vendor packages or versions not affected by this CVE.; Prioritize externally exposed services that process untrusted encoded input.; Check operating system and appliance vendor advisories for backported OpenSSL fixes..
