Potential out-of-bounds read with a malformed ELF file and the HashTable API.

Affected versions of this crate only validated the index argument of HashTable::getbucket and HashTable::getchain against the input-controlled bucketcount and chaincount fields, but not against the size of the ELF section. As a result, a malformed ELF file could trigger out-of-bounds reads in a...

kernel: udp: Set SOCK_RCU_FREE earlier in udp_lib_get_port()

In the Linux kernel, the following vulnerability has been resolved: udp: Set SOCKRCUFREE earlier in udplibgetport. syzkaller triggered the warning 0 in udpv4earlydemux. In udpv46earlydemux and sklookup, we do not touch the refcount of the looked-up sk and use sockpfree as skb-destructor, so we...

eap-7: heap exhaustion via deserialization

A flaw was found in EAP-7 during deserialization of certain classes, which permits instantiation of HashMap and HashTable with no checks on resources consumed. This issue could allow an attacker to submit malicious requests using these classes, which could eventually exhaust the heap and result i...
