Several vulnerabilities were discovered in dwarfutils, a tool and library for reading/consuming and writing/producing DWARF debugging information. The Common Vulnerabilities and Exposures project identifies the following issues :

CVE-2015-8538

A specially crafted ELF file can cause a segmentation fault.

CVE-2015-8750

A specially crafted ELF file can cause a NULL pointer dereference.

CVE-2016-2050

Out-of-bounds write

CVE-2016-2091

Out-of-bounds read

CVE-2016-5034

Out-of-bounds write

CVE-2016-5036

Out-of-bounds read

CVE-2016-5038

Out-of-bounds read

CVE-2016-5039

Out-of-bounds read

CVE-2016-5042

A specially crafted DWARF section can cause an infinite loop, reading from increasing memory addresses until the application crashes.

For Debian 7 'Wheezy', these problems have been fixed in version 20120410-2+deb7u2.

We recommend that you upgrade your dwarfutils packages.

  - Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2024-2002. Reason: This candidate is a     duplicate of CVE-2024-2002. Notes: All CVE users should reference CVE-2024-2002 instead of this candidate.
