The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2018-1122 top read its configuration from the current working directory if no $HOME was configured. If top were started from a directory writable by the attacker (such as /tmp) this could result in local privilege escalation. CVE-2018-1123 Denial of service against the ps invocation of another user. CVE-2018-1124 An integer overflow in the file2strvec() function of libprocps could result in local privilege escalation. CVE-2018-1125 A stack-based buffer overflow in pgrep could result in denial of service for a user using pgrep for inspecting a specially crafted process. CVE-2018-1126 Incorrect integer size parameters used in wrappers for standard C allocators could cause integer truncation and lead to integer overflow issues. For Debian 7 "Wheezy", these problems have been fixed in version 1:3.3.3.3+deb7u1. We recommend that you upgrade your procps packages.
