CVE-2018-1124

procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows 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.

This update for procps fixes the following issues:

procps was updated to 3.3.15. (bsc#1092100)

Following security issues were fixed:

• 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).

Also this non-security issue was fixed:

• Fix CPU summary showing old data. (bsc#1121753)

• library: Increment to 8:0:1 No removals, no new functions Changes: slab and pid structures

• pgrep: warn about 15+ char name only if -f not used
• pgrep/pkill: only match in same namespace by default
• pidof: specify separator between pids
• pkill: Return 0 only if we can kill process
• pmap: fix duplicate output line under '-x' option
• ps: avoid eip/esp address truncations

• top: show fewer memory decimal places (configurable)
• top: provide command line switch for memory scaling
• top: provide command line switch for CPU States
• top: provides more accurate cpu usage at startup
• top: display NUMA node under which a thread ran
