SUSE CVE-2015-5291

Heap-based buffer overflow in PolarSSL 1.x before 1.2.17 and ARM mbed TLS formerly PolarSSL 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service client crash and possibly execute arbitrary code via a long hostname to the server name indication SNI...

SUSE CVE-2022-35409

An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server that causes a heap-based buffer over-read of up to 255 bytes. This can cause a server crash or possibly information...
