Multiple cross-site request forgery (CSRF) vulnerabilities in Ubiquiti Networks UniFi Controller before 3.2.1 allow remote attackers to hijack the authentication of administrators for requests that (1) create a new admin user via a request to api/add/admin; (2) have unspecified impact via a request to api/add/wlanconf; change the guest (3) password, (4) authentication method, or (5) restricted subnets via a request to api/set/setting/guest_access; (6) block, (7) unblock, or (8) reconnect users by MAC address via a request to api/cmd/stamgr; change the syslog (9) server or (10) port via a request to api/set/setting/rsyslogd; (11) have unspecified impact via a request to api/set/setting/smtp; change the syslog (12) server, (13) port, or (14) authentication settings via a request to api/cmd/cfgmgr; or (15) change the Unifi Controller name via a request to api/set/setting/identity.
Sander Bos discovered a time of check to time of use (TOCTTOU) vulnerability in apport that allowed a user to cause core files to be written in arbitrary directories.
Sander Bos discovered Apport mishandled crash dumps originating from containers. This could be used by a local attacker to generate a crash report for a privileged process that is readable by an unprivileged user.
Kevin Backhouse discovered an integer overflow in bson_ensure_space, as used in whoopsie.
Sander Bos discovered Apport's lock file was in a world-writable directory which allowed all users to prevent crash handling.
Kevin Backhouse discovered that apport would read a user-supplied configuration file with elevated privileges. By replacing the file with a symbolic link, a user could get apport to read any file on the system as root, with unknown consequences.
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.5.0.20723. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the conversion of DXF files to PDF. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-8774.
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.5.0.20723. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DXF files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-8775.
