The ai_cmd utility executes with full root permissions. It pipes socket inputs directly to popen(), paving the way for unauthenticated users to execute arbitrary root commands.
The local MQTT broker does not enforce topic-level Access Control Lists (ACLs). This allows any client to subscribe using wildcard characters (# or +) to enumerate hidden network devices or publish rogue control commands.
OpenStack Ironic before 35.0.2 allows a malicious authenticated project admin or manager to read local files on the Ironic conductor via a pxe_template.
HTML::Entities versions before 3.84 for Perl read freed heap memory in _decode_entities.
The XS routine backing HTML::Entities::_decode_entities cached a pointer (repl) into the entity-value SV returned by hv_fetch on the entity2char hash. When the input SV was identical to a value SV in that hash, and that value contained its own key as an entity reference, a later call to grow_gap() reallocated the SV's PV buffer and freed the backing allocation that repl still pointed into. The subsequent copy loop read repl_len bytes from the freed allocation.
The read may disclose adjacent heap contents into the destination SV.
An out-of-bounds read vulnerability in the morse.ko HaLow Wi-Fi kernel driver in Morse Micro HaLowLink 2 software versions prior to 2.11.12 allows an unauthenticated attacker within radio range to disclose a small amount of kernel heap memory or cause a Denial of Service (kernel oops/panic) via a crafted 802.11ah beacon or probe response frame containing a malformed Vendor Information Element. The function morse_vendor_find_vendor_ie() does not validate the IE length against the expected structure size before its result is passed to morse_vendor_rx_caps_ops_ie() and morse_vendor_fill_sta_vendor_info(), which read at fixed offsets into the IE data. Because the length check only requires the IE to be longer than 3 bytes, an attacker can supply an undersized IE, causing a heap out-of-bounds read of up to 9 bytes. No authentication, association, or user interaction is required.
Net::Async::Statsd::Client versions through 0.005 for Perl allow metric injections.
The metric names are not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics.
