As per upstream samba advisory:

All versions of Samba from 3.5.0 to 4.2.0rc4 are vulnerable to an unexpected code execution vulnerability in the smbd file server daemon.

A malicious client could send packets that may set up the stack in such a way that the freeing of memory in a subsequent anonymous netlogon packet could allow execution of arbitrary code. This code would execute with root privileges.

Unspecified vulnerability in Oracle Java SE 5.0u75, 6u85, 7u72, and 8u25 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to RMI.

Unspecified vulnerability in Oracle Java SE 6u85, 7u72, and 8u25 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Hotspot.

The exception::getTraceAsString function in Zend/zendexceptions.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 allows remote attackers to execute arbitrary code via an unexpected data type, related to a "type confusion" issue.

The PHPIncompleteClass function in ext/standard/incompleteclass.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an unexpected data type, related to a "type confusion" issue.

Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier and 5.7.11 and earlier allows remote attackers to affect confidentiality, integrity, and availability via vectors related to Pluggable Authentication.

redhat-upgrade-tool: Does not check GPG signatures when upgrading versions

Oracle MySQL through 5.5.52, 5.6.x through 5.6.33, and 5.7.x through 5.7.15; MariaDB before 5.5.51, 10.0.x before 10.0.27, and 10.1.x before 10.1.17; and Percona Server before 5.5.51-38.1, 5.6.x before 5.6.32-78.0, and 5.7.x before 5.7.14-7 allow local users to create arbitrary configurations and bypass certain protection mechanisms by setting generallogfile to a my.cnf configuration. NOTE: this can be leveraged to execute arbitrary code with root privileges by setting malloclib. NOTE: the affected MySQL version information is from Oracle's October 2016 CPU. Oracle has not commented on third-party claims that the issue was silently patched in MySQL 5.5.52, 5.6.33, and 5.7.15.

The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow.

Use-after-free while manipulating XSL in XSLT documents

A potential use-after-free found through fuzzing during DOM manipulation of SVG content.

The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation.

A use-after-free vulnerability in the Media Decoder when working with media files when some events are fired after the media elements are freed from memory.

Use-after-free while manipulating DOM events and removing audio elements due to errors in the handling of node adoption.

Use-after-free resulting in potentially exploitable crash when manipulating DOM subtrees in the Editor.

Memory safety bugs were reported in Thunderbird 45.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.

A use-after-free vulnerability when using an incorrect URL during the reloading of a docshell. This results in a potentially exploitable crash.

A use-after-free vulnerability with content viewer listeners that results in a potentially exploitable crash.

A use-after-free vulnerability during video control operations when a "<track>" element holds a reference to an older window if that window has been replaced in the DOM. This results in a potentially exploitable crash. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.

A flaw in netfilter could allow a network-connected attacker to infer openvpn connection endpoint information for further use in traditional network attacks.

A use-after-free vulnerability can occur in the Fetch API when the worker or the associated window are freed when still in use, resulting in a potentially exploitable crash.

A use-after-free vulnerability can occur during WebRTC connections when interacting with the DTMF timers. This results in a potentially exploitable crash.

A flaw was reported in kernel TCP subsystem while calculating a packet round trip time, when a sysctl parameter (/proc/sys/net/ipv4/tcpminrttwlen) when is set wrongly. This causes an integer over flaw which can lead to a Denial Of Service (DOS) attack.

SQL injection vector when manually quoting values for sqlsrv extension, using null byte

Heap-based buffer overflow in the PackBitsPreEncode function in tifpackbits.c in bmp2tiff in libtiff 4.0.6 and earlier allows remote attackers to execute arbitrary code or cause a denial of service via a large width field in a BMP image.

It has been discovered that redhat-certification does not properly sanitize paths in rhcertStore.py:saveResultsFile. A remote attacker could use this flaw to overwrite any file, potentially gaining remote code execution.

A flaw was found in http-proxy-agent versions before 2.1.0. The http-proxy-agent passes auth option to the Buffer constructor without proper sanitization, resulting in DoS and uninitialized memory leak in setups where an attacker could submit typed input to the 'auth' parameter (e.g. JSON).

A flaw was found in mbsync versions prior to 1.4.4. Due to inadequate handling of extremely large (>=2GiB) IMAP literals, malicious or compromised IMAP servers, and hypothetically even external email senders, could cause several different buffer overflows, which could conceivably be exploited for remote code execution.

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass -dSAFER restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.
