Updated p11-kit packages fix security vulnerabilities

Publication date: 17 Jan 2021
Type: security
Affected Mageia releases : 7
CVE: CVE-2020-29361 , CVE-2020-29362 , CVE-2020-29363

Description

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).
