An integer overflow flaw was found in the way the lzo library decompressed certain archives compressed with the LZO algorithm. An attacker could create a specially crafted LZO-compressed input that, when decompressed by an application using the lzo library, would cause that application to crash or, potentially, execute arbitrary code.

Updated liblzo packages fix security vulnerability :

An integer overflow in liblzo before 2.07 allows attackers to cause a denial of service or possibly code execution in applications performing LZO decompression on a compressed payload from the attacker (CVE-2014-4607).

(CVE-2014-4607 - reserved)

The remote NewStart CGSL host, running version MAIN 6.06 (SP), has grub2 packages installed that are affected by multiple vulnerabilities:

  - Multiple integer underflows in Grub2 1.98 through 2.02 allow physically proximate attackers to bypass     authentication, obtain sensitive information, or cause a denial of service (disk corruption) via backspace     characters in the (1) grub_username_get function in grub-core/normal/auth.c or the (2) grub_password_get     function in lib/crypto.c, which trigger an Off-by-two or Out of bounds overwrite memory error.
    (CVE-2015-8370)

  - Integer overflow in the LZO algorithm variant in Oberhumer liblzo2 and lzo-2 before 2.07 on 32-bit     platforms might allow remote attackers to execute arbitrary code via a crafted Literal Run.
    (CVE-2014-4607)

  - A flaw was found in the grub2-set-bootflag utility of grub2. A local attacker could run this utility under     resource pressure (for example by setting RLIMIT), causing grub2 configuration files to be truncated and     leaving the system unbootable on subsequent reboots. (CVE-2019-14865)

  - A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper     the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to     load an untrusted or modified kernel, an attacker would first need to establish access to the system such     as gaining physical access, obtain the ability to alter a pxe-boot network, or have remote access to a     networked system with root access. With this access, an attacker could then craft a string to cause a     buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The     highest threat from this vulnerability is to data confidentiality and integrity as well as system     availability. (CVE-2020-10713)

  - In grub2 versions before 2.06 the grub memory allocator doesn't check for possible arithmetic overflows on     the requested allocation size. This leads the function to return invalid memory allocations which can be     further used to cause possible integrity, confidentiality and availability impacts during the boot     process. (CVE-2020-14308)

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

An integer overflow flaw was found in the way the lzo library decompressed certain archives compressed with the LZO algorithm. An attacker could create a specially crafted LZO-compressed input that, when decompressed by an application using the lzo library, would cause that application to crash or, potentially, execute arbitrary code.
(CVE-2014-4607)

For the update to take effect, all services linked to the lzo library must be restarted or the system rebooted.

bnc#883947: CVE-2014-4607: lzo: DoS or possible RCE by allowing an attacker to change controllflow

Don A. Bailey from Lab Mouse Security discovered an integer overflow flaw in the way the lzo library decompressed certain archives compressed with the LZO algorithm. An attacker could create a specially crafted LZO-compressed input that, when decompressed by an application using the lzo library, would cause that application to crash or, potentially, execute arbitrary code.

This updates icecream to the current version from upstream git repository. It drops the bundled minilzo library, which had a vulnerability. Instead the system lzo library is used. (CVE-2014-4607)

LibVNCServer was updated to version 0.9.10 to fix several security and non-security issues.

The following issues were fixed :

  - Remove xorg-x11-devel from buildRequires, X libraries     are not directly used/linked

  - libvncserver-0.9.10-ossl.patch: Update, do not     RAND_load_file('/dev/urandom', 1024) if the the PRNG is     already seeded. (It always is on linux)

  - Update to version 0.9.10

  + Moved the whole project from sourceforge to     https://libvnc.github.io/.

  + Cleaned out the autotools build system which now uses     autoreconf.

  + Updated noVNC HTML5 client to latest version.

  + Split out x11vnc sources into separate repository at     https://github.com/LibVNC/x11vnc

  + Split out vncterm sources into separate repository at     https://github.com/LibVNC/vncterm

  + Split out VisualNaCro sources into separate repository     at https://github.com/LibVNC/VisualNaCro

  + Merged Debian patches.

  + Fixed some security-related buffer overflow cases.

  + Added compatibility headers to make     LibVNCServer/LibVNCClient build on native Windows 8.

  + Update LZO to version 2.07, fixing CVE-2014-4607.

  + Merged patches from KDE/krfb.

  + Can now do IPv6 without IPv4.

  + Fixed a use-after-free issue in scale.c.

  - Update Url and download source to new project home

  - Remove LibVNCServer-0.9.9-no_x11vnc.patch; upstream     splited it out of main tarball

  - Rebase libvncserver-ossl.patch to upstream changes >     libvncserver-0.9.10-ossl.patch

  - Remove linuxvnc subpackage; like x11vnc, it has been     splited out but is depreciated and unmaintained.

The remote host is affected by the vulnerability described in GLSA-201701-14 (LZO: Multiple vulnerabilities)

    LZO is vulnerable to an integer overflow condition in the       &ldquo;lzo1x_decompress_safe&rdquo; function which could result in a possible       buffer overrun when processing maliciously crafted compressed input data.
  Impact :

    A remote attacker could send specially crafted compressed input data       possibly resulting in a Denial of Service condition or arbitrary code       execution.
  Workaround :

    There is no known workaround at this time.
