openSUSE Security Update: Security update for procps
______________________________________________________________________________

Announcement ID: openSUSE-SU-2019:2376-1
Rating: important
References: #1092100 #1121753
Cross-References: CVE-2018-1122 CVE-2018-1123 CVE-2018-1124
CVE-2018-1125 CVE-2018-1126
Affected Products:
openSUSE Leap 15.1
______________________________________________________________________________

An update that fixes 5 vulnerabilities is now available.

Description:

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

* top: eliminated minor libnuma memory leak
* 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
* top: fix argument parsing quirk resulting in SEGV
