   An update that fixes 5 vulnerabilities is now available.

Description:

   This update for procps fixes the following security issues:

   - CVE-2018-1122: Prevent local privilege escalation in top. If a user ran
     top with HOME unset in an attacker-controlled directory, the attacker
     could have achieved privilege escalation by exploiting one of several
     vulnerabilities in the config_file() function (bsc#1092100).
   - CVE-2018-1123: Prevent denial of service in ps via mmap buffer overflow.
     Inbuilt protection in ps maped a guard page at the end of the overflowed
     buffer, ensuring that the impact of this flaw is limited to a crash
     (temporary denial of service) (bsc#1092100).
   - CVE-2018-1124: Prevent multiple integer overflows leading to a heap
     corruption in file2strvec function. This allowed a privilege escalation
     for a local attacker who can create entries in procfs by starting
     processes, which could result in crashes or arbitrary code execution in
     proc utilities run by
     other users (bsc#1092100).
   - CVE-2018-1125: Prevent stack buffer overflow in pgrep. This
     vulnerability was mitigated by FORTIFY limiting the impact to a crash
     (bsc#1092100).
   - CVE-2018-1126: Ensure correct integer size in proc/alloc.* to prevent
     truncation/integer overflow issues (bsc#1092100).
