Today we are releasing MS15-011 & MS15-014 which harden group policy and address network access vulnerabilities that can be used to achieve remote code execution (RCE) in domain networks. The MS15-014 update addresses an issue in Group Policy update which can be used to disable client-side global SMB Signing requirements, bypassing an existing security feature built into the product.

XML external entity vulnerability in the Extended Computer Aided Test Tool (eCATT) in SAP NetWeaver AS ABAP 7.31 and earlier allows remote attackers to access arbitrary files via a crafted XML request, related to ECATT_DISPLAY_XMLSTRING_REMOTE, aka SAP Note 2016638.

Integer underflow in the ksba_oid_to_str function in Libksba before 1.3.2, as used in GnuPG, allows remote attackers to cause a denial of service (crash) via a crafted OID in a (1) S/MIME message or (2) ECC based OpenPGP data, which triggers a buffer overflow.

The cdf_check_stream_offset function in cdf.c in file before 5.19, as used in the Fileinfo component in PHP before 5.4.30 and 5.5.x before 5.5.14, relies on incorrect sector-size data, which allows remote attackers to cause a denial of service (application crash) via a crafted stream offset in a CDF file.

The internal DNS server in Samba 4.x before 4.0.18 does not check the QR field in the header section of an incoming DNS message before sending a response, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged response packet that triggers a communication loop, a related issue to CVE-1999-0103.

Samba 3.6.6 through 3.6.23, 4.0.x before 4.0.18, and 4.1.x before 4.1.8, when a certain vfs shadow copy configuration is enabled, does not properly initialize the SRV_SNAPSHOT_ARRAY response field, which allows remote authenticated users to obtain potentially sensitive information from process memory via a (1) FSCTL_GET_SHADOW_COPY_DATA or (2) FSCTL_SRV_ENUMERATE_SNAPSHOTS request.

The am function in lib/hub/commands.rb in hub before 1.12.1 allows local users to overwrite arbitrary files via a symlink attack on a temporary patch file.

The hash functionality in json-c before 0.12 allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted JSON data, involving collisions.

Samba 3.x before 3.6.23, 4.0.x before 4.0.16, and 4.1.x before 4.1.6 does not enforce the password-guessing protection mechanism for all interfaces, which makes it easier for remote attackers to obtain access via brute-force ChangePasswordUser2 (1) SAMR or (2) RAP attempts.

Apache Santuario XML Security for Java before 1.5.6, when applying Transforms, allows remote attackers to cause a denial of service (memory consumption) via crafted Document Type Definitions (DTDs), related to signatures.
