Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2015-1788)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application in the BN_GF2m_mod_inv function in crypto/bn/bn_gf2m.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
2) Buffer overflow (CVE-ID: CVE-2015-1789)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the X509_cmp_time function in crypto/x509/x509_vfy.c. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.
3) Race condition (CVE-ID: CVE-2015-1791)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the ssl3_get_new_session_ticket function in ssl/s3_clnt.c in OpenSSL. A local user can exploit the race and cause a denial of service (double free and application crash) or possibly have unspecified other impact by providing a NewSessionTicket during an attempt to reuse a ticket that had been obtained earlier.
4) Race condition (CVE-ID: CVE-2015-3216)
The vulnerability allows a local user to perform a denial of service attack.
The vulnerability exists due to a race condition in a certain Red Hat patch to the PRNG lock implementation in the ssleay_rand_bytes function in OpenSSL. A local user can exploit the race and cause a denial of service (application crash) by establishing many TLS sessions to a multithreaded server, leading to use of a negative value for a certain length field.
