moderate: p11-kit/trousers security update
moderate
An update for p11-kit/trousers is now available for NewStart CGSL MAIN 6.02.
NewStart Security has rated this update as having a security impact of moderate. A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
p11-kit: The p11-kit-devel package contains libraries and header files for developing applications that use p11-kit.
trousers: TrouSerS is an implementation of the Trusted Computing Group's Software Stack (TSS) specification. You can use TrouSerS to write applications that make use of your TPM hardware. TPM hardware can create, store and use RSA keys securely (without ever being exposed in memory), verify a platform's software state using cryptographic hashes and more.
Security Fix(es):
p11-kit: An issue was discovered in p11-kit 0.21.1 through 0.23.21. A heap-based buffer over-read has been discovered in the RPC protocol used by thep11-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)
p11-kit: An issue was discovered in p11-kit 0.23.6 through 0.23.21. 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)
p11-kit: An issue was discovered in p11-kit 0.21.1 through 0.23.21. 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)
p11-kit: bugfix
trousers: An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges, the creation of the system.data file is prone to symlink attacks. The tss user can be used to create or corrupt existing files, which could possibly lead to a DoS attack.(CVE-2020-24332)
trousers: An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges, the tss user still has read and write access to the /etc/tcsd.conf file (which contains various settings related to this daemon).(CVE-2020-24331)
trousers: An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges instead of by the tss user, it fails to drop the root gid privilege when no longer needed.(CVE-2020-24330)
trousers: bugfix
