URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display, allowing for domain name spoofing attacks in the location bar.

Event handlers on "marquee" elements were executed despite a strict Content Security Policy (CSP) that disallowed inline JavaScript. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.

On pages containing an iframe, the "data:" protocol can be used to create a modal alert that will render over arbitrary domains following page navigation, spoofing of the origin of the modal alert from the iframe content. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

Using SVG filters that don't use the fixed point math implementation on a target iframe, a malicious page can extract pixel values from a targeted user. This can be used to extract history information and read text values across domains. This violates same-origin policy and leads to information disclosure.

Video files loaded video captions cross-origin without checking for the presence of CORS headers permitting such cross-origin use, leading to potential information disclosure for video captions.

Certain response codes in FTP connections can result in the use of uninitialized values for ports in FTP operations.

A flaw was found in systemd-journald. An out-of-bounds read when parsing a crafted syslog message that could lead to information disclosure.

A race condition was found in util-linux before 2.32.1 in the way su handled the management of child processes. A local authenticated attacker could use this flaw to kill other processes with root privileges under specific conditions.

A vulnerability was found in Linux kernel. There is an information leak in file sound/core/timer.c of the latest mainline Linux kernel. The stack object “r1” has a total size of 32 bytes. Its field “event” and “val” both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.

It was reported [1] that iptables can allow protocols that do not have a protocol handler kernel module loaded.

Given following iptables ruleset: -P FORWARD DROP -A FORWARD -m sctp --dport 9 -j ACCEPT -A FORWARD -p tcp --dport 80 -j ACCEPT -A FORWARD -p tcp -m conntrack -m state ESTABLISHED,RELATED -j ACCEPT

One would assume that this allows SCTP on port 9 and TCP on port 80. Unfortunately, if the SCTP conntrack module is not loaded, this allows all SCTP communication to pass through, i.e. -p sctp -j ACCEPT

A local user can trigger a flaw in the Linux kernel's handling of key lookups in the keychain subsystem.

The keyrejectandlink() function contains an error in which a key-lookup can fail and in an attempt to cache the failed lookup may attempt to free memory which can still be in use.

This could crash the system or at worse free a memory block which would then be re-used by another kernel mechanism causing a user after free.

In elfutils 0.175, a negative-sized memcpy is attempted in elfcvtnote in libelf/notexlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).

An issue was discovered in sd-bus in systemd 239. busprocessobject() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic).

It was discovered that the DNS client implementation in the JNDI component of OpenJDK did not use random source ports when sending out DNS queries. This would make it easier for a remote attacker to spoof responses to those queries.

It was discovered that the I18n component of OpenJDK could use an untrusted search path when loading resource bundle classes. A local attacker could possibly use this flaw to execute arbitrary code as another local user by making their Java application load an attacker controlled class file.

It was discovered that the LdapLoginModule class in the LDAP component of OpenJDK failed to properly encode special characters in user names when adding them to LDAP search query. A remote attacker could possibly use this flaw to manipulate LDAP queries performed by the LdapLoginModule class.

It was discovered that the Hotspot component of OpenJDK failed to properly validate uses of the invokeinterface Java Virtual Machine instruction. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.

It was discovered that multiple encryption key classes (DESKey, DESedeKey, PBEKey, PBKDF2KeyImpl) in the crypto provider in the Libraries component of OpenJDK did not properly synchronize access to their internal key data from multiple threads. This could possibly cause a multi-threaded Java application to apply weak encryption to data because of use of key that was zeroed out during object finalization.

A flaw was found in Poppler 0.72.0. The PDFDoc::setup class in PDFDoc.cc allows attackers to cause a denial-of-service (application crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF file in which an xref data structure is mishandled during extractPDFSubtype processing.

An issue was discovered in Poppler 0.71.0. There is a memory leak in GfxColorSpace::setDisplayProfile in GfxState.cc, as demonstrated by pdftocairo.

An issue was discovered in mspack/chmd.c in libmspack before 0.7alpha. ...

A flaw was found in Mozilla Thunderbird before version 52.9. Decrypted S/MIME parts, when included in HTML crafted for an attack, can leak plaintext when included in a a HTML reply/forward.

A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory.

A use-after-free vulnerability was found in a network namespaces code affecting the Linux kernel since v4.0-rc1 through v4.15-rc5. The function getnetnsbyid() does not check for the net::count value after it has found a peer network in netnsids idr which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.

Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 allow remote attackers to bypass the Same Origin Policy and read the Location object via a prototype property-injection attack that defeats certain protection mechanisms for this object.

Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 do not prevent use of the valueOf method to shadow the location object (aka window.location), which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via vectors involving a plugin.

Unspecified vulnerability in Oracle MySQL 5.5.48 and earlier, 5.6.29 and earlier, and 5.7.11 and earlier allows local users to affect integrity and availability via vectors related to Federated.
