Description
This security bulletin contains information about 6 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) NULL pointer dereference (CVE-ID: CVE-2015-1790)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the PKCS7_dataDecodefunction in crypto/pkcs7/pk7_doit.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
4) 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.
5) Resource management error (CVE-ID: CVE-2015-1792)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the do_free_upto function in crypto/cms/cms_smime.c in OpenSSL. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack via vectors that trigger a NULL value of a BIO data structure.
6) Buffer overflow (CVE-ID: CVE-2014-8176)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
The dtls1_clear_queues function in ssl/d1_lib.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h frees data structures without considering that application data can arrive between a ChangeCipherSpec message and a Finished message, which allows remote DTLS peers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unexpected application data.
