Affected Mageia releases : 7
CVE: CVE-2020-29361 , CVE-2020-29362 , CVE-2020-29363
Multiple integer overflows have been discovered in the array allocations in the p11-kit library and the p11-kit list command, where overflow checks are missing before calling realloc or calloc (CVE-2020-29361). A heap-based buffer over-read has been discovered in the RPC protocol used by the p11-kit server/remote commands and the client library. When the remote entity supplies a byte array through a serialized PKCS#11 function call, the receiving entity may allow the reading of up to 4 bytes of memory past the heap allocation (CVE-2020-29362). A heap-based buffer overflow has been discovered in the RPC protocol used by p11-kit server/remote commands and the client library. When the remote entity supplies a serialized byte array in a CK_ATTRIBUTE, the receiving entity may not allocate sufficient length for the buffer to store the deserialized value (CVE-2020-29363).
