  "description": "Issue summary: The POLY1305 MAC (message authentication code)implementationcontains a bug that might corrupt the internal state of applicationsrunningon PowerPC CPU based platforms if the CPU provides vector instructions.Impact summary: If an attacker can influence whether the POLY1305 MACalgorithm is used, the application state might be corrupted with variousapplication dependent consequences.The POLY1305 MAC (message authentication code) implementation in OpenSSLforPowerPC CPUs restores the contents of vector registers in a different orderthan they are saved. Thus the contents of some of these vector registersare corrupted when returning to the caller. The vulnerable code is usedonlyon newer PowerPC processors supporting the PowerISA 2.07 instructions.The consequences of this kind of internal application state corruption canbe various - from no consequences, if the calling application does notdepend on the contents of non-volatile XMM registers at all, to the worstconsequences, where the attacker could get complete control of theapplicationprocess. However unless the compiler uses the vector registers for storingpointers, the most likely consequence, if any, would be an incorrect resultof some application dependent calculations or a crash leading to a denialofservice.The POLY1305 MAC algorithm is most frequently used as part of theCHACHA20-POLY1305 AEAD (authenticated encryption with associated data)algorithm. The most common usage of this AEAD cipher is with TLS protocolversions 1.2 and 1.3. If this cipher is enabled on the server a maliciousclient can influence whether this AEAD cipher is used. This implies thatTLS server applications using OpenSSL can be potentially impacted. Howeverwe are currently not aware of any concrete application that would beaffectedby this issue therefore we consider this a Low severity security issue.",
