- More information:
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:
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.
Denial of service against the ps invocation of another user.
An integer overflow in the file2strvec() function of libprocps could result in local privilege escalation.
A stack-based buffer overflow in pgrep could result in denial of service for a user using pgrep for inspecting a specially crafted process.
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.
