A vulnerability classified as problematic has been found in Andries Brouwer man 1.5h1/1.5i/1.5i2/1.5j/1.5k. This affects the function my_xsprintf of the component Quote Handler. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

man before 1.5l allows attackers to execute arbitrary code via a malformed man file with improper quotes, which causes the my_xsprintf function to return a string with the value "unsafe," which is then executed as a program via a system call if it is in the search path of the user who runs man.
