  script_tag(name:"insight", value:"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).");
