MuJS 1.3.6 before 1.3.9 Heap Out-of-Bounds Read/Write via Array.prototype.sort

MuJS 1.3.6 before 1.3.9 contains a heap out-of-bounds read and write vulnerability in Array.prototype.sort that allows attackers to corrupt memory by inflating a simple array's length. Attackers can supply JavaScript that enlarges a dense array's length and calls sort, causing Ap_sort_cmp and Ap_sort_swap to access slots past the buffer and crash the process.

A logical issue in O_getOwnPropertyDescriptor() in Artifex MuJS 1.0.0 through 1.3.x before 1.3.2 allows an attacker to achieve Remote Code Execution through memory corruption, via the loading of a crafted JavaScript file.

An integer overflow vulnerability was observed in the regemit function in regexp.c in Artifex Software, Inc. MuJS before fa3d30fd18c348bb4b1f3858fb860f4fcd4b2045. The attack requires a regular expression with nested repetition. A successful exploitation of this issue can lead to code execution or a denial of service (buffer overflow) condition.

regexp.c in Artifex Software, Inc. MuJS allows attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to regular expression compilation.

Heap-based buffer overflow in the js_stackoverflow function in jsrun.c in Artifex Software, Inc. MuJS allows attackers to have unspecified impact by leveraging an error when dropping extra arguments to lightweight functions.

The chartorune function in Artifex Software MuJS allows attackers to cause a denial of service (out-of-bounds read) via a * (asterisk) at the end of the input.

Heap-based buffer overflow in the Fp_toString function in jsfunction.c in Artifex Software MuJS allows attackers to cause a denial of service (crash) via crafted input.

Integer overflow in the js_regcomp function in regexp.c in Artifex Software, Inc. MuJS before commit b6de34ac6d8bb7dd5461c57940acfbd3ee7fd93e allows attackers to cause a denial of service (application crash) via a crafted regular expression.

Artifex Software MuJS allows attackers to cause a denial of service (crash) via vectors related to incomplete escape sequences. NOTE: this vulnerability exists due to an incomplete fix for CVE-2016-7563.

An issue was discovered in Artifex Software, Inc. MuJS before 4006739a28367c708dea19aeb19b8a1a9326ce08. The jsR_setproperty function in jsrun.c lacks a check for a negative array length. This leads to an integer overflow in the js_pushstring function in jsrun.c when parsing a specially crafted JS file.

An issue was discovered in Artifex Software, Inc. MuJS before 8f62ea10a0af68e56d5c00720523ebcba13c2e6a. The MakeDay function in jsdate.c does not validate the month, leading to an integer overflow when parsing a specially crafted JS file.

An out-of-bounds read vulnerability was observed in Sp_replace_regexp function of Artifex Software, Inc. MuJS before 5000749f5afe3b956fc916e407309de840997f4a. A successful exploitation of this issue can lead to code execution or denial of service condition.

Artifex Software, Inc. MuJS before 5008105780c0b0182ea6eda83ad5598f225be3ee allows context-dependent attackers to conduct "denial of service (application crash)" attacks by using the "malformed labeled break/continue in JavaScript" approach, related to a "NULL pointer dereference" issue affecting the jscompile.c component.

A buffer overflow vulnerability was observed in divby function of Artifex Software, Inc. MuJS before 8c805b4eb19cf2af689c860b77e6111d2ee439d5. A successful exploitation of this issue can lead to code execution or denial of service condition.

A use-after-free vulnerability was observed in Rp_toString function of Artifex Software, Inc. MuJS before 5c337af4b3df80cf967e4f9f6a21522de84b392a. A successful exploitation of this issue can lead to code execution or denial of service condition.

Artifex Software, Inc. MuJS before a0ceaf5050faf419401fe1b83acfa950ec8a8a89 allows context-dependent attackers to obtain sensitive information by using the "crafted JavaScript" approach, related to a "Buffer Over-read" issue.

Artifex Software, Inc. MuJS before a5c747f1d40e8d6659a37a8d25f13fb5acf8e767 allows context-dependent attackers to obtain sensitive information by using the "opname in crafted JavaScript file" approach, related to an "Out-of-Bounds read" issue affecting the jsC_dumpfunction function in the jsdump.c component.

Buffer-overflow in jsdtoa.c in Artifex MuJS in versions 1.0.1 to 1.1.1. An integer overflow happens when js_strtod() reads in floating point exponent, which leads to a buffer overflow in the pointer *d.

In Artifex MuJS through 1.2.0, jsP_dumpsyntax in jsdump.c has a NULL pointer dereference, as demonstrated by mujs-pp.

compile in regexp.c in Artifex MuJS through 1.2.0 results in stack consumption because of unlimited recursion, a different issue than CVE-2019-11413.
