It was discovered that pcrecompile function in pcrecompile.c in PCRE before 8.38 mishandles certain [: nesting, which allows remote attackers to cause a denial of service (CPU consumption) or possibly have unspecified other impact via a crafted regular expression.

Heap-based buffer overflow in the iscsiaioioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call.

Buffer overflow vulnerabilities in functions pnggetPLTE/pngsetPLTE, allowing remote attackers to cause DoS to application or have unspecified other impact. These functions failed to check for an out-of-range palette when reading or writing PNG files with a bitdepth less than 8. Some applications might read the bit depth from the IHDR chunk and allocate memory for a 2^N entry palette, while libpng can return a palette with up to 256 entries even when the bit depth is less than 8.

Affected versions of libpng are before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19.

A malformed query response received by a recursive server in response to a query of RTYPE ANY could trigger an assertion failure while named is attempting to add the RRs in the query response to the cache. While the combination of properties which triggers the assertion should not occur in normal traffic, it is potentially possible for the assertion to be triggered deliberately by an attacker sending a specially-constructed answer having the required properties, after having engineered a scenario whereby an ANY query is sent to the recursive server for the target QNAME. A recursive server will itself only send a query of type ANY if it receives a client query of type ANY for a QNAME for which it has no RRsets at all in cache, otherwise it will respond to the client with the the RRsets that it has available.

This vulnerability occurs during the processing of an answer packet received in response to a query. As a result, recursive servers are at the greatest risk; authoritative servers are at risk only to the extent that they perform a limited set of queries.

This description is borrowed from the upstream advisory.

A defect in BIND's handling of responses containing a DNAME answer can cause a resolver to exit after encountering an assertion failure in db.c or resolver.c

During processing of a recursive response that contains a DNAME record in the answer section, BIND can stop execution after encountering an assertion error in resolver.c (error message: "INSIST((valoptions & 0x0002U) != 0) failed") or db.c (error message: "REQUIRE(targetp != ((void )0) && targetp == ((void )0)) failed").

A server encountering either of these error conditions will stop, resulting in denial of service to clients. The risk to authoritative servers is minimal; recursive servers are chiefly at risk.

Multiple memory leaks in kadmin/server/serverstubs.c in kadmind in MIT Kerberos 5 (aka krb5) before 1.13.4 and 1.14.x before 1.14.1 allow remote authenticated users to cause a denial of service (memory consumption) via a request specifying a NULL principal name.

Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before 5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack.

ISC BIND 9.x before 9.9.9-P2, 9.10.x before 9.10.4-P2, and 9.11.x before 9.11.0b2, when lwresd or the named lwres option is enabled, allows remote attackers to cause a denial of service (daemon crash) via a long request that uses the lightweight resolver protocol.
