A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.27 handled component references in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened. Se encontró un fallo de desreferencia de puntero NULL en la manera en que Jasper versiones anteriores a 2.0.27, manejaban las referencias de componentes en el decodificador de formato de imagen JP2. Un archivo de imagen JP2 especialmente diseñado podría causar que una aplicación que usa la biblioteca Jasper se bloquee al abrirse • https://bugzilla.redhat.com/show_bug.cgi?id=1939233 • CWE-476: NULL Pointer Dereference •

A flaw was found in libmicrohttpd. A missing bounds check in the post_process_urlencoded function leads to a buffer overflow, allowing a remote attacker to write arbitrary data in an application that uses libmicrohttpd. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Only version 0.9.70 is vulnerable.

The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this. Se detectó que el parche para CVE-2020-17380/CVE-2020-25085 era ineficaz, por lo que QEMU era vulnerable a problemas de acceso de lectura y escritura fuera de límites que se encontraban anteriormente en el código de emulación del controlador SDHCI. Este fallo permite a un invitado privilegiado malicioso bloquear el proceso QEMU en el host, resultando en una denegación de servicio o una posible ejecución de código. • https://bugzilla.redhat.com/show_bug.cgi?id=1928146 https://lists.debian.org/debian-lts-announce/2021/04/msg00009.html https://security.gentoo.org/glsa/202208-27 https://security.netapp.com/advisory/ntap-20210507-0001 https://www.openwall.com/lists/oss-security/2021/03/09/1 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

A flaw was found in http-proxy-agent, prior to version 2.1.0. It was discovered http-proxy-agent passes an auth option to the Buffer constructor without proper sanitization. This could result in a Denial of Service through the usage of all available CPU resources and data exposure through an uninitialized memory leak in setups where an attacker could submit typed input to the auth parameter. Se encontró un fallo en http-proxy-agent, versiones anteriores a 2.1.0. Se detectó que http-proxy-agent pasa una opción de autenticación al constructor de Buffer sin un saneamiento apropiado. • https://bugzilla.redhat.com/show_bug.cgi?id=1567245 https://www.npmjs.com/advisories/607 • CWE-665: Improper Initialization •
CVSS: 6.0EPSS: 0%CPEs: 8EXPL: 0CVE-2021-3416 – QEMU: net: Infinite loop in loopback mode may lead to stack overflow
https://notcve.org/view.php?id=CVE-2021-3416
A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the host resulting in DoS scenario. Se encontró un posible desbordamiento de la pila por medio de un problema de bucle infinito en varios emuladores de NIC de QEMU en versiones hasta 5.2.0 incluyéndola. El problema ocurre en el modo loopback de una NIC en donde son omitidas las comprobaciones DMA reentrantes. • https://bugzilla.redhat.com/show_bug.cgi?id=1932827 https://lists.debian.org/debian-lts-announce/2021/04/msg00009.html https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html https://security.gentoo.org/glsa/202208-27 https://security.netapp.com/advisory/ntap-20210507-0002 https://www.openwall.com/lists/oss-security/2021/02/26/1 https://access.redhat.com/security/cve/CVE-2021-3416 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
