Posted on: 02/26/2019 08:34 AM

The following updates has been released for Debian GNU/Linux:

Debian GNU/Linux 7 Extended LTS:
ELA-84-1 gnutls26 security update
ELA-85-1 elfutils security update

Debian GNU/Linux 8 LTS:
DLA 1688-1: waagent update
DLA 1689-1: elfutils security update

ELA-84-1 gnutls26 security update
Package: gnutls26
Version: 2.12.20-8+deb7u6
Related CVE: CVE-2017-7869 CVE-2017-5335 CVE-2017-5336 CVE-2017-5337
GNUTLS-SA-2017-2: CVE-2017-5335, CVE-2017-5336, CVE-2017-5337

It was found that decoding a specially crafted OpenPGP certificate could
lead to heap and stack overflows. This may cause a denial-of-service
(out-of-memory error and crash) or lead to other unspecified impact by
remote attackers. This affects only applications which utilize the OpenPGP
certificate functionality of GnuTLS.

CVE-2017-7869

It was found that decoding a specially crafted OpenPGP certificate could
lead to (A) an integer overflow, resulting in an invalid memory write, (B)
a null pointer dereference resulting in a server crash, and (C) a large
allocation, resulting in a server out-of-memory condition. These affect
only applications which utilize the OpenPGP certificate functionality of
GnuTLS.
For Debian 7 Wheezy, these problems have been fixed in version 2.12.20-8+deb7u6.

We recommend that you upgrade your gnutls26 packages.

ELA-85-1 elfutils security update
Package: elfutils
Version: 0.152-1+wheezy2

Several issues in elfutils, a collection of utilities to handle ELF objects, have been found either by fuzzing or by using an AddressSanitizer.

CVE-2019-7665 Due to a heap-buffer-overflow problem in function elf32_xlatetom() a crafted ELF input can cause segmentation faults.

CVE-2019-7150 Add sanity check for partial core file dynamic data read.

CVE-2019-7149 Due to a heap-buffer-overflow problem in function read_srclines() a crafted ELF input can cause segmentation faults.

CVE-2018-18521 By using a crafted ELF file, containing a zero sh_entsize, a divide-by-zero vulnerability could allow remote attackers to cause a denial of service (application crash).

CVE-2018-18520 By fuzzing an Invalid Address Deference problem in function elf_end has been found.

CVE-2018-18310 By fuzzing an Invalid Address Read problem in eu-stack has been found.

CVE-2018-16062 By using an AddressSanitizer a heap-buffer-overflow has been found.

CVE-2017-7613 By using fuzzing it was found that an allocation failure was not handled properly.

CVE-2017-7612 By using a crafted ELF file, containing an invalid sh_entsize, a remote attackers could cause a denial of service (application crash).

CVE-2017-7611 By using a crafted ELF file a remote attackers could cause a denial of service (application crash).

CVE-2017-7610 By using a crafted ELF file a remote attackers could cause a denial of service (application crash).

CVE-2017-7608 By fuzzing a heap based buffer overflow has been detected.

For Debian 7 Wheezy, these problems have been fixed in version 0.152-1+wheezy2.

We recommend that you upgrade your elfutils packages.
