Описание
Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i). Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x).

Отчет
This flaw only affects applications which are compiled with OpenSSL and using EVP_CipherUpdate, EVP_EncryptUpdate or EVP_DecryptUpdate functions. When specially-crafted values are passed to these functions, it can cause the application to crash or behave incorrectly. OpenSSL in Red Hat Enterprise Linux 9 was marked as not affected as its already fixed in RHEL9 Alpha release.
