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.(CVE-2022-30974)

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.(CVE-2016-7504)

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.(CVE-2016-9108)

This leads to an integer overflow in the js_pushstring function in jsrun.c when parsing a specially crafted JS file.(CVE-2017-5627)

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.(CVE-2016-7506)

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.(CVE-2016-9017)

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.(CVE-2017-5628)

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.

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.(CVE-2016-9136)

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.

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.

These are all security issues fixed in the mujs-1.2.0-3.1 package on the GA media of openSUSE Tumbleweed.

It was discovered that MuJS did not correctly handle try/finally statements, which could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2021-45005)

Han Zheng discovered that MuJS did not correctly handle recursion, which could lead to stack exhaustion. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-30974)

Han Zheng discovered that MuJS did not correctly handle certain memory operations. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-30975)
