https://notcve.org/view.php?id=CVE-2021-20266
A flaw was found in RPM's hdrblobInit() in lib/header.c. This flaw allows an attacker who can modify the rpmdb to cause an out-of-bounds read. The highest threat from this vulnerability is to system availability. Se detectó un fallo en RPM en la función hdrblobInit() en el archivo lib/header.c. Este fallo permite a un atacante que puede modificar el rpmdb causar una lectura fuera de límites. • https://bugzilla.redhat.com/show_bug.cgi?id=1927741 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TMGXO3W6DHPO62GJ4VVF5DEUX5DRUR5K https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VHRPNBCRPDJHHQE3MBPSZK4H7X2IM7AC https://security.gentoo.org/glsa/202107-43 https://access.redhat.com/security/cve/CVE-2021-20266 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2021-20271
A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is to data integrity, confidentiality, and system availability. Se detectó un fallo en la funcionalidad de comprobación de firmas de RPM cuando se lee un archivo de paquete. Este fallo permite a un atacante que pueda convencer a una víctima de instalar un paquete aparentemente verificable, cuyo encabezado de firma fue modificado, causar una corrupción de la base de datos de RPM y ejecutar código. • https://bugzilla.redhat.com/show_bug.cgi?id=1934125 https://github.com/rpm-software-management/rpm/commit/d6a86b5e69e46cc283b1e06c92343319beb42e21 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TMGXO3W6DHPO62GJ4VVF5DEUX5DRUR5K https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VHRPNBCRPDJHHQE3MBPSZK4H7X2IM7AC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YILPBTPSBRYL4POBI3F4YUSVPSOQNJBY https://security.gentoo.org/glsa/ • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2017-7500
It was found that rpm did not properly handle RPM installations when a destination path was a symbolic link to a directory, possibly changing ownership and permissions of an arbitrary directory, and RPM files being placed in an arbitrary destination. An attacker, with write access to a directory in which a subdirectory will be installed, could redirect that directory to an arbitrary location and gain root privilege. Se ha detectado que rpm no manejaba correctamente las instalaciones RPM cuando una ruta de destino era un enlace simbólico a un directorio, posiblemente cambiando la propiedad y los permisos de un directorio arbitrario y los archivos RPM se colocaban en un destino arbitrario. Un atacante con acceso de escritura a un directorio en el que se instalará un subdirectorio podría redirigir ese directorio a una ubicación arbitraria y obtener privilegios root. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-7500 https://github.com/rpm-software-management/rpm/commit/c815822c8bdb138066ff58c624ae83e3a12ebfa9 https://github.com/rpm-software-management/rpm/commit/f2d3be2a8741234faaa96f5fd05fdfdc75779a79 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2017-7501
It was found that versions of rpm before 4.13.0.2 use temporary files with predictable names when installing an RPM. An attacker with ability to write in a directory where files will be installed could create symbolic links to an arbitrary location and modify content, and possibly permissions to arbitrary files, which could be used for denial of service or possibly privilege escalation. Se ha descubierto que las versiones de rpm anteriores a la 4.13.0.2 emplean archivos temporales con nombres predecibles al instalar un RPM. Un atacante que pueda escribir en un directorio en el que se instalarán archivos podría crear enlaces simbólicos en una localización arbitraria y modificar contenido y, probablemente, permisos en archivos arbitrarios. Esto podría emplearse para provocar una denegación de servicio o un posible escalado de privilegios. • https://github.com/rpm-software-management/rpm/commit/404ef011c300207cdb1e531670384564aae04bdc https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://security.gentoo.org/glsa/201811-22 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2014-8118
Integer overflow in RPM 4.12 and earlier allows remote attackers to execute arbitrary code via a crafted CPIO header in the payload section of an RPM file, which triggers a stack-based buffer overflow. Desbordamiento de enteros en RPM 4.12 y anteriores permite a atacantes remotos ejecutar código arbitrario a través de una cabecera CPIO manipulada en la sección 'payload' de un ficheros RPM, lo que provoca un desbordamiento de buffer basado en pila. • http://advisories.mageia.org/MGASA-2014-0529.html http://rhn.redhat.com/errata/RHSA-2014-1976.html http://www.debian.org/security/2015/dsa-3129 http://www.mandriva.com/security/advisories?name=MDVSA-2014:251 http://www.mandriva.com/security/advisories?name=MDVSA-2015:056 https://security.gentoo.org/glsa/201811-22 https://access.redhat.com/security/cve/CVE-2014-8118 https://bugzilla.redhat.com/show_bug.cgi?id=1168715 • CWE-121: Stack-based Buffer Overflow CWE-189: Numeric Errors •
