contents of memory beyond the\nend of the input buffer. More typically such ASN.1 elements would instead be\ntruncated.\n\nAn integer truncation in OpenSSL's ASN.1 decoder causes the content length of\nan ASN.1 primitive element to be mishandled when it exceeds 2 gigabytes. In the\nworst case the truncated length is treated as a request to scan the binary\ncontent for a terminating zero byte, possibly causing OpenSSL to read either\nless than or beyond the end of the allocated buffer.\n\nApplications that pass attacker-supplied data to d2i_X509(), d2i_PKCS7(), or\nany other d2i_* decoding function are affected. OpenSSL's own command-line\ntools are not vulnerable, as data read through the BIO layer is checked before\nit reaches the affected code. The issue only affects 64-bit Unix and Unix-like\nplatforms; 32-bit platforms and 64-bit Windows are not affected.\n\nThe FIPS modules in 4.0, 3.6, 3.5, 3.4 and 3.0 are not affected by this issue,\nas

application crash\nand a Denial of Service.\n\nThe CMS PasswordRecipientInfo.keyDerivationAlgorithm field is defined as\nOPTIONAL in the ASN.1 specification and may therefore be absent in specially\ncrafted inputs. During the password-based CMS decryption the OpenSSL\nCMS implementation dereferences this field without first checking whether it\nwas present.\n\nAn attacker who supplies such a CMS message to an application performing\npassword-based CMS decryption can trigger an application crash, leading to\na Denial of Service.\n\nApplications that process password-encrypted CMS messages may be affected.\n\nThe FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this\nissue, as the affected code is outside the OpenSSL FIPS module boundary.", "title": "Vulnerability description"
