Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2803 advisory.

- An exploitable integer overflow vulnerability exists when creating a new RGB Surface in SDL 2.0.5. A specially crafted file can cause an integer overflow resulting in too little memory being allocated which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability. (CVE-2017-2888)

- SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has a heap-based buffer overflow in SDL_FillRect in video/SDL_surface.c. (CVE-2019-7637)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the libsdl2 packages.

For Debian 9 stretch, these problems have been fixed in version 2.0.5+dfsg1-2+deb9u2.
