https://notcve.org/view.php?id=CVE-2020-11793
A use-after-free issue exists in WebKitGTK before 2.28.1 and WPE WebKit before 2.28.1 via crafted web content that allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash). Hay un uso de la memoria previamente liberada en WebKitGTK versiones anteriores a la versión 2.28.1 y WPE WebKit versiones anteriores a la versión 2.28.1, por medio de un contenido web especialmente diseñado que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de la memoria y bloqueo de aplicación). A use-after-free flaw exists in WebKitGTK. This flaw allows remote attackers to execute arbitrary code or cause a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3P4YISPE5QX4YD54GDRZIH2X5RCH3QGW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K3MQTRC6ITFTVS5R5Z24PMJS6FXJKGRD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UTKY2MWP6PB6TE3ZKOOMKX7HZUCQNYF6 https://security.gentoo.org/glsa/202006-08 https://usn.ubuntu.com/4331-1 https://webkitg • CWE-416: Use After Free •

CVSS: 9.8EPSS: 1%CPEs: 10EXPL: 0CVE-2019-12519 – squid: improper check for new member in ESIExpression::Evaluate allows for stack buffer overflow
https://notcve.org/view.php?id=CVE-2019-12519
An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00018.html http://www.openwall.com/lists/oss-security/2020/04/23/1 https://gitlab.com/jeriko.one/security/-/blob/master/squid/CVEs/CVE-2019-12519.txt https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://security.gentoo.org/glsa/202005-05 https://security.netapp.com/advisory/ntap-20210205-0006 https://usn.ubuntu.com/4356-1 https://www.debian.org/security/2020/dsa-4682 https://a • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 5.9EPSS: 4%CPEs: 10EXPL: 0CVE-2019-12521 – squid: Off-by-one error in addStackElement allows for heap buffer overflow and crash
https://notcve.org/view.php?id=CVE-2019-12521
An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00018.html http://www.openwall.com/lists/oss-security/2020/04/23/1 https://gitlab.com/jeriko.one/security/-/blob/master/squid/CVEs/CVE-2019-12521.txt https://lists.debian.org/debian-lts-announce/2020/07/msg00009.html https://security.gentoo.org/glsa/202005-05 https://security.netapp.com/advisory/ntap-20210205-0006 https://usn.ubuntu.com/4356-1 https://www.debian.org/security/2020/dsa-4682 https://a • CWE-122: Heap-based Buffer Overflow CWE-193: Off-by-one Error CWE-787: Out-of-bounds Write •
