![]() The FIPS provider is not affected by this issue.Ĭacti is an open source operational monitoring and fault management framework. ![]() Runtime by setting the environment variable OPENSSL_ia32cap: However we are currently not aware ofĪny concrete application that would be affected by this issue therefore weĬonsider this a Low severity security issue.Īs a workaround the AVX512-IFMA instructions support can be disabled at ![]() This implies that server applications using Versions 1.2 and 1.3 and a malicious client can influence whether this AEADĬipher is used by the server. The most common usage of this AEAD cipher is with TLS protocol ![]() The POLY1305 MAC algorithm is most frequently used as part of theĬHACHA20-POLY1305 AEAD (authenticated encryption with associated data)Īlgorithm. If any, would be an incorrect result of some application dependentĬalculations or a crash leading to a denial of service. The attacker cannot put arbitrary values inside, the most likely consequence, However given the contents of the registers are just zeroized so The consequences of this kind of internal application state corruption canīe various - from no consequences, if the calling application does notĭepend on the contents of non-volatile XMM registers at all, to the worstĬonsequences, where the attacker could get complete control of the application The vulnerable code is used only on newer x86_64 processors The caller all the XMM registers are set to zero rather than restoring their When calculating the MAC of data larger than 64 bytes. Not save the contents of non-volatile XMM registers on Windows 64 platform The POLY1305 MAC (message authentication code) implementation in OpenSSL does State might be corrupted with various application dependent consequences. Impact summary: If in an application that uses the OpenSSL library an attackerĬan influence whether the POLY1305 MAC algorithm is used, the application Windows 64 platform when running on newer X86_64 processors supporting the Issue summary: The POLY1305 MAC (message authentication code) implementationĬontains a bug that might corrupt the internal state of applications on the ![]()
