Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the procps packages.

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.
