The issue is related to an uncontrolled search path element in wpa supplicant, allowing a local unprivileged attacker to escalate privileges to the user that wpa supplicant runs as, usually root. Membership in the netdev group or access to the dbus interface of wpa supplicant allows an unprivileged user to specify an arbitrary path to a module to be loaded by the wpa supplicant process. The estimated number of potentially affected devices is in the millions.

The issue is related to a memory corruption problem, specifically a use-after-free error, which may lead to arbitrary code execution. This can be exploited by a remote attacker to execute arbitrary code.

A remote code execution issue exists due to the scripting engine's handling of objects in memory. This could lead to memory corruption, allowing an attacker to execute arbitrary code in the context of the current user. If the user has administrative rights, the attacker could gain control of the system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights.

This issue allows remote attackers to disclose sensitive information on vulnerable installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of PDF documents due to the lack of proper validation of user-supplied data. This can result in a read past the end of an allocated object, potentially allowing an attacker to execute code in the context of the current process when combined with other vulnerabilities.

This issue allows remote attackers to execute arbitrary code on vulnerable installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of `CPDF Object` objects due to the lack of validating the existence of an object prior to performing operations on it. An attacker can leverage this to execute code under the context of the current process.
