  script_tag(name:"insight", value:"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 Debian 7 Wheezy, these problems have been fixed in version 1:3.3.3.3+deb7u1.

We recommend that you upgrade your procps packages.

The Debian LTS team would like to thank Abhijith PA for preparing this update.
