An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58.
Improper input validation in the Auto-Discovery component of Nagios XI before 5.7.5 allows an authenticated attacker to execute remote code.
An issue was discovered on Western Digital My Cloud NAS devices before 5.04.114. They allow remote code execution with resultant escalation of privileges.
Grafana before 7.1.0-beta 1 allows XSS via a query alias for the ElasticSearch datasource.
debian/sympa.postinst for the Debian Sympa package before 6.2.40~dfsg-7 uses mode 4755 for sympa_newaliases-wrapper, whereas the intended permissions are mode 4750 (for access by the sympa group)
Sympa through 6.2.57b.2 allows a local privilege escalation from the sympa user account to full root access by modifying the sympa.conf configuration file (which is owned by sympa) and parsing it through the setuid sympa_newaliases-wrapper executable.
openmediavault before 4.1.36 and 5.x before 5.5.12 allows authenticated PHP code injection attacks, via the sortfield POST parameter of rpc.php, because json_encode_safe is not used in config/databasebackend.inc. Successful exploitation allows arbitrary command execution on the underlying operating system as root.
CodeLathe FileCloud before 20.2.0.11915 allows username enumeration.
A buffer overflow was found in perl-DBI < 1.643 in DBI.xs. A local attacker who is able to supply a string longer than 300 characters could cause an out-of-bounds write, affecting the availability of the service or integrity of data.
The modprobe child process in the ./debian/patches/load_ppp_generic_if_needed patch file incorrectly handled module loading. A local non-root attacker could exploit the MODPROBE_OPTIONS environment variable to read arbitrary root files. Fixed in 2.4.5-5ubuntu1.4, 2.4.5-5.1ubuntu2.3+esm2, 2.4.7-1+2ubuntu1.16.04.3, 2.4.7-2+2ubuntu1.3, 2.4.7-2+4.1ubuntu5.1, 2.4.7-2+4.1ubuntu6. Was ZDI-CAN-11504.
