In Ubuntu's accountsservice an unprivileged local attacker can trigger a use-after-free vulnerability in accountsservice by sending a D-Bus message to the accounts-daemon process. en Ubuntu AccountsService un atacante local no privilegiado puede desencadenar una vulnerabilidad de uso de memoria previamente liberada en accountsservice enviando mensajes D-Bus al accounts-daemon process. • https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/2024182 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-3297 https://securitylab.github.com/advisories/GHSL-2023-139_accountsservice https://ubuntu.com/security/notices/USN-6190-1 • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 0CVE-2021-3939 – Free of static data in accountsservice
https://notcve.org/view.php?id=CVE-2021-3939
Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1. Unas modificaciones específicas de Ubuntu a accountsservice (en el archivo de parche debian/patches/0010-set-language.patch) causaron la liberación de la variable fallback_locale, que apunta al almacenamiento estático, en la función user_change_language_authorized_cb. Esto es accesible por medio de la función dbus SetLanguage. • http://packetstormsecurity.com/files/172848/Ubuntu-accountsservice-Double-Free-Memory-Corruption.html https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/1950149 https://ubuntu.com/security/notices/USN-5149-1 • CWE-590: Free of Memory not on the Heap CWE-763: Release of Invalid Pointer or Reference •
CVSS: 3.3EPSS: 0%CPEs: 1EXPL: 1CVE-2020-16126 – accountsservice drops ruid, allows unprivileged users to send it signals
https://notcve.org/view.php?id=CVE-2020-16126
An Ubuntu-specific modification to AccountsService in versions before 0.6.55-0ubuntu13.2, among other earlier versions, improperly dropped the ruid, allowing untrusted users to send signals to AccountService, thus stopping it from handling D-Bus messages in a timely fashion. Una modificación específica de Ubuntu para AccountsService en versiones anteriores a 0.6.55-0ubuntu13.2, entre otras versiones anteriores, eliminó incorrectamente el ruid, lo que permitió a usuarios que no eran de confianza enviar señales a AccountService, impidiendo así que manejara los mensajes D-Bus de manera oportuna • https://securitylab.github.com/advisories/GHSL-2020-187-accountsservice-drop-privs-DOS • CWE-269: Improper Privilege Management •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 1CVE-2020-16127 – accountsservice .pam_environment infinite loop
https://notcve.org/view.php?id=CVE-2020-16127
An Ubuntu-specific modification to AccountsService in versions before 0.6.55-0ubuntu13.2, among other earlier versions, would perform unbounded read operations on user-controlled ~/.pam_environment files, allowing an infinite loop if /dev/zero is symlinked to this location. Una modificación específica de Ubuntu para AccountsService en versiones anteriores a 0.6.55-0ubuntu13.2, entre otras versiones anteriores, llevaría a cabo operaciones de lectura ilimitadas en archivos ~/.pam_environment controlados por el usuario, permitiendo un bucle infinito si /dev/zero está enlazado simbólicamente a esta ubicación • https://securitylab.github.com/advisories/GHSL-2020-187-accountsservice-drop-privs-DOS • CWE-20: Improper Input Validation CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
