openssl: integer underflow leading to buffer overflow in base64 decoding
Published Mar 19, 2015

HIGHCVSS 2.0
EPSS 44.50%
Description
Integer underflow in the EVP_DecodeUpdate function in crypto/evp/encode.c in the base64-decoding implementation in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted base64 data that triggers a buffer overflow.
