Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27. A remote attacker can use a crafted ECC point to trigger heap-based buffer overflow and execute arbitrary code on the target system.
