Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow.

CVE-2016-2195 [CRITICAL] CWE-119 GHSA-7gxp-rgh3-mj5p: Integer overflow in the PointGFp constructor in Botan before 1
Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow.

CVE-2016-2195 [CRITICAL] CVE-2016-2195: Integer overflow in the PointGFp constructor in Botan before 1
Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow. The bigint_mul and bigint_sqr functions received the size of the output buffer, but only used it to dispatch to a faster algorithm in cases where there was sufficient output space to call an unrolled multiplication function. The result is a heap overflow accessible via ECC point decoding, which accepted untrusted inputs. This is likely exploitable for remote code execution.
No detection rules found.

2016-02-01 (CVE-2016-2196): Overwrite in P-521 reduction
The P-521 reduction function would overwrite zero to one word following the allocated block. This could potentially result in remote code execution or a crash. Found with AFL
Introduced in 1.11.10, fixed in 1.11.27
2016-02-01 (CVE-2016-2195): Heap overflow on invalid ECC point
The PointGFp constructor did not check that the affine coordinate arguments were less than the prime, but then in curve multiplication assumed that both arguments if multiplied would fit into an integer twice the size of the prime.
The bigint_mul and bigint_sqr functions received the size of the output buffer, but only used it to dispatch to a faster algorithm in c
