SynopsisThe remote Debian host is missing a security update.
DescriptionThe 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 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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected libprocps0, libprocps0-dev, and procps packages.
