An exploitable buffer overflow vulnerability exists in the XCF property handling functionality of SDL_image 2.0.1. A specially crafted xcf file can cause a stack-based buffer overflow resulting in potential code execution. An attacker can provide a specially crafted XCF file to trigger this vulnerability.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An exploitable code execution vulnerability exists in the XCF image rendering functionality of Simple
    DirectMedia Layer SDL2_image-2.0.2. A specially crafted XCF image can cause an out-of-bounds write on the
    heap, resulting in code execution. An attacker can display a specially crafted image to trigger this
    vulnerability. (CVE-2018-3839)

  - An exploitable buffer overflow vulnerability exists in the XCF property handling functionality of
    SDL_image 2.0.1. A specially crafted xcf file can cause a stack-based buffer overflow resulting in
    potential code execution. An attacker can provide a specially crafted XCF file to trigger this
    vulnerability. (CVE-2017-2887)

  - An exploitable code execution vulnerability exists in the ILBM image rendering functionality of
    SDL2_image-2.0.2. A specially crafted ILBM image can cause a heap overflow resulting in code execution. An
    attacker can display a specially crafted image to trigger this vulnerability. (CVE-2017-12122)

  - An exploitable code execution vulnerability exists in the ILBM image rendering functionality of
    SDL2_image-2.0.2. A specially crafted ILBM image can cause a stack overflow resulting in code execution.
    An attacker can display a specially crafted image to trigger this vulnerability. (CVE-2017-14440)

  - An exploitable code execution vulnerability exists in the ICO image rendering functionality of
    SDL2_image-2.0.2. A specially crafted ICO image can cause an integer overflow, cascading to a heap
    overflow resulting in code execution. An attacker can display a specially crafted image to trigger this
    vulnerability. (CVE-2017-14441)

Security fix for CVE-2018-3977

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that there was a buffer overflow vulnerability in sdl-image1.2, an image loading library.

A specially crafted .xcf file could cause a stack-based buffer overflow resulting in potential code execution.

For Debian 7 'Wheezy', this issue has been fixed in sdl-image1.2 version 1.2.12-2+deb7u1.

We recommend that you upgrade your sdl-image1.2 packages.
