CVE-2018-1126
Debian Bug : 899170
The Qualys Research Labs discovered multiple vulnerabilities in procps,
a set of command line and full screen utilities for browsing procfs. 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 the oldstable distribution (jessie), these problems have been fixed
in version 2:3.3.9-9+deb8u1.
For the stable distribution (stretch), these problems have been fixed in
version 2:3.3.12-3+deb9u1.
We recommend that you upgrade your procps packages.
