CVE-2020-1751 – glibc: array overflow in backtrace functions for powerpc
https://notcve.org/view.php?id=CVE-2020-1751
An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the frame address, resulting in a denial of service or potential code execution. The highest threat from this vulnerability is to system availability. Se encontró una vulnerabilidad de escritura fuera de límites en glibc versiones anteriores a 2.31, cuando se manejaban trampolines de señal en PowerPC. Concretamente, la función backtrace no comprueba apropiadamente los límites de la matriz cuando almacena la dirección de la trama, resultando en una denegación de servicio o a una posible ejecución de código. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1751 https://security.gentoo.org/glsa/202006-04 https://security.netapp.com/advisory/ntap-20200430-0002 https://sourceware.org/bugzilla/show_bug.cgi?id=25423 https://usn.ubuntu.com/4416-1 https://access.redhat.com/security/cve/CVE-2020-1751 https://bugzilla.redhat.com/show_bug.cgi?id=1810719 • CWE-787: Out-of-bounds Write •

CVE-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 •
