Alpine: libcrypto3, multiple openssl packages: security update to 1.0.2-r2 (deprecated)

critical Tenable Cloud Security Plugin ID 400994

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The DTLS implementation in OpenSSL before 1.1.0 does not properly restrict the lifetime of queue entries
associated with unused out-of-order messages, which allows remote attackers to cause a denial of service
(memory consumption) by maintaining many crafted DTLS sessions simultaneously, related to d1_lib.c,
statem_dtls.c, statem_lib.c, and statem_srvr.c. (CVE-2016-2179)

- The Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0 mishandles early use of a new
epoch number in conjunction with a large sequence number, which allows remote attackers to cause a denial
of service (false-positive packet drops) via spoofed DTLS records, related to rec_layer_d1.c and
ssl3_record.c. (CVE-2016-2181)

- The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0 does not properly validate division
results, which allows remote attackers to cause a denial of service (out-of-bounds write and application
crash) or possibly have unspecified other impact via unknown vectors. (CVE-2016-2182)

- The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before 1.1.0 does not consider the HMAC size
during validation of the ticket length, which allows remote attackers to cause a denial of service via a
ticket that is too short. (CVE-2016-6302)

- Integer overflow in the MDC2_Update function in crypto/mdc2/mdc2dgst.c in OpenSSL before 1.1.0 allows
remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly have
unspecified other impact via unknown vectors. (CVE-2016-6303)
