| A number of security vulnerabilities in the Graphite 2 library including out-of-bounds reads, buffer overflow reads and writes, and the use of uninitialized memory. These issues were addressed in Graphite 2 version 1.3.10. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2. |
| An out-of-bounds read vulnerability with the Opus encoder when the number of channels in an audio stream changes while the encoder is in use. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2. |
| 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. |
| The libxul.so!gfxContext::Polygon 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 memory, cause a denial of service (out-of-bounds read and application crash), or possibly bypass the Same Origin Policy via vectors involving MathML polygon rendering. |
| Heap-based buffer overflow in the read_u32 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 cause a denial of service (out-of-bounds read and application crash) via a crafted JPEG image. |
| When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. |
| An out-of-bounds read in WebGL with a maliciously crafted "ImageInfo" object during WebGL operations. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2. |
| A buffer overflow can occur when manipulating Accessible Rich Internet Applications (ARIA) attributes within the DOM. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. |
| An out-of-bounds read occurs when applying style rules to pseudo-elements, such as ::first-line, using cached style data. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. |
| 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. |
| A buffer overflow will occur when viewing a certificate in the certificate manager if the certificate has an extremely long object identifier (OID). This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. |
| An out-of-bounds read while processing SVG content in "ConvolvePixel". This results in a crash and also allows for otherwise inaccessible memory being copied into SVG graphic content, which could then displayed. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53. |
| An out-of-bounds read when an HTTP/2 connection to a servers sends "DATA" frames with incorrect data content. This leads to a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53. |
| A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. |
| A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix reading strings from synthetic events
The follow commands caused a crash:
# cd /sys/kernel/tracing
# echo 's:open char file[]' > dynamic_events
# echo 'hist:keys=common_pid:file=filename:onchange($file).trace(open,$file)' > events/syscalls/sys_enter_openat/trigger'
# echo 1 > events/synthetic/open/enable
BOOM!
The problem is that the synthetic event field "char file[]" will read
the value given to it as a string without any memory checks to make sure
the address is valid. The above example will pass in the user space
address and the sythetic event code will happily call strlen() on it
and then strscpy() where either one will cause an oops when accessing
user space addresses.
Use the helper functions from trace_kprobe and trace_eprobe that can
read strings safely (and actually succeed when the address is from user
space and the memory is mapped in).
Now the above can show:

| The fetch function in file thinkphp\library\think\Template.php in ThinkPHP 5.0.24 allows attackers to read arbitrary files via crafted file path in a template value. |
| In the Linux kernel, the following vulnerability has been resolved:
cpufreq: qcom: fix writes in read-only memory region
This commit fixes a kernel oops because of a write in some read-only memory:
[ 9.068287] Unable to handle kernel write to read-only memory at virtual address ffff800009240ad8
..snip..
[ 9.138790] Internal error: Oops: 9600004f [#1] PREEMPT SMP
..snip..
[ 9.269161] Call trace:
[ 9.276271] __memcpy+0x5c/0x230
[ 9.278531] snprintf+0x58/0x80
[ 9.282002] qcom_cpufreq_msm8939_name_version+0xb4/0x190
[ 9.284869] qcom_cpufreq_probe+0xc8/0x39c
..snip..
The following line defines a pointer that point to a char buffer stored
in read-only memory:
char *pvs_name = "speedXX-pvsXX-vXX";
This pointer is meant to hold a template "speedXX-pvsXX-vXX" where the
XX values get overridden by the qcom_cpufreq_krait_name_version function. Since
the template is actually stored in read-only memory, when the function
executes the following call we get an oops:
snprintf(*pvs_name, sizeof("speedXX-pvsXX-vXX"), "speed%d-pvs%d-v%d",
speed, pvs, pvs_ver);
To fix this issue, we instead store the template name onto the stack by
using the following syntax:
char pvs_name_buffer[] = "speedXX-pvsXX-vXX";
Because the `pvs_name` needs to be able to be assigned to NULL, the
template buffer is stored in the pvs_name_buffer and not under the
pvs_name variable. |
| Out-of-bounds Read in Shelly Pro 3EM (before v1.4.4) allows Overread Buffers. |
| glib-networking's OpenSSL backend fails to properly check the return value of a call to BIO_write(), resulting in an out of bounds read. |
