A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the next_input_file function Un uso de memoria previamente liberada en el applet awk de Busybox conduce a la denegación de servicio y posiblemente a una ejecución de código cuando es procesado un patrón awk diseñado en la función next_input_file • https://claroty.com/team82/research/unboxing-busybox-14-vulnerabilities-uncovered-by-claroty-jfrog https://jfrog.com/blog/unboxing-busybox-14-new-vulnerabilities-uncovered-by-claroty-and-jfrog https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6T2TURBYYJGBMQTTN2DSOAIQGP7WCPGV https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UQXGOGWBIYWOIVXJVRKHZR34UMEHQBXS https://security.netapp.com/advisory/ntap-20211223-0002 • CWE-416: Use After Free •
CVE-2019-5747 – Cisco Device Hardcoded Credentials / GNU glibc / BusyBox
https://notcve.org/view.php?id=CVE-2019-5747
An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP client, server, and/or relay) might allow a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679. Se ha descubierto un problema en BusyBox hasta la versión 1.30.0. • http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://seclists.org/fulldisclosure/2019/Sep/7 https://bugs.busybox.net/show_bug.cgi?id=11506 https://git.busybox.net/busybox/commit/?id=74d9f1ba37010face4bd1449df4d60dd84450b06 https://seclists.org/bugtraq/2019/Sep/7 https://usn.ubuntu.com/3935-1 • CWE-125: Out-of-bounds Read •
CVE-2018-20679 – Cisco Device Hardcoded Credentials / GNU glibc / BusyBox
https://notcve.org/view.php?id=CVE-2018-20679
An issue was discovered in BusyBox before 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP server, client, and relay) allows a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to verification in udhcp_get_option() in networking/udhcp/common.c that 4-byte options are indeed 4 bytes. Se ha descubierto un problema en versiones anteriores a la 1.30.0 de BusyBox. Una lectura fuera de límites en los componentes udhcp (consumidos por el servidor, cliente y relays DHCP) permite que un atacante remoto filtre información sensible de la pila mediante el envío de un mensaje DHCP manipulado. • http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://seclists.org/fulldisclosure/2019/Sep/7 https://bugs.busybox.net/show_bug.cgi?id=11506 https://busybox.net/news.html https://git.busybox.net/busybox/commit/?id=6d3b4bb24da9a07c263f3c1acf8df85382ff562c https://seclists.org/bugtraq/2019/Sep/7 https://usn.ubuntu.com/3935-1 • CWE-125: Out-of-bounds Read •
