Ampere Altra devices before 1.08g and Ampere Altra Max devices before 2.05a allow attackers to control the predictions for return addresses and potentially hijack code flow to execute arbitrary code via a side-channel attack, aka a “Retbleed” issue.

Discourse through 2.8.7 allows admins to send invitations to arbitrary email addresses at an unlimited rate.

The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface.

An issue was discovered in Softing OPC UA C++ SDK before 6.10. A buffer overflow or an excess allocation happens due to unchecked array and matrix bounds in structure data types.

Exim before 4.95 has a heap-based buffer overflow for the alias list in host_name_lookup in host.c when sender_host_name is set.

Exim before 4.96 has an invalid free in pam_converse in auths/call_pam.c because store_free is not used after store_malloc.
