It was discovered that there were two vulnerabilities in libextractor, a library to obtain metadata from files of arbitrary type.

  • A stack-based buffer overflow in unzip.c.
    (CVE-2018-14346)

  • An infinite loop vulnerability in mpeg_extractor.c.
    (CVE-2018-14347)

For Debian 8 ‘Jessie’, these issues have been fixed in libextractor version 1:1.3-2+deb8u2.

We recommend that you upgrade your libextractor packages.

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.
