Computer vulnerabilities of EMC NetWorker
Linux kernel: privilege escalation via Copy On Write, Dirty COW

Description of the vulnerability
The Linux kernel supports the Copy On Write operation, which is used to copy memory only when it is modified.
However, a local attacker can manipulate the memory, so the COW operation writes in Read Only memory.
A local attacker can therefore generate a memory corruption via a Copy On Write on the Linux kernel, in order to trigger a denial of service, and possibly to run code.

Flexera InstallShield, JRSoft Inno Setup: code execution via DLL-planting
Synthesis of the vulnerability
An attacker can create a malicious DLL for Flexera InstallShield or JRSoft Inno Setup, in order to run code with administrator privileges.
Impacted products: NetWorker, FortiClient, DB2 UDB, Notes, Tivoli Storage Manager, WebSphere MQ, Notepad++, PuTTY, X2GoClient.
Severity: 3/4.
Consequences: administrator access/rights, privileged access/rights, user access/rights.
Provenance: document.
Creation date: 09/05/2016.
Revisions dates: 02/06/2016, 06/07/2016.
Identifiers: 1610582, 1978168, 1978363, 1979808, 1980839, 1982467, 1982741, 1982809, 1983796, 1983797, 1983813, 1983814, 1983815, 1984184, 1984743, 1984863, 494999, CVE-2016-2542, ESA-2017-008, FG-IR-16-046, VIGILANCE-VUL-19558.
Description of the vulnerability
The products Flexera InstallShield and JRSoft Inno Setup are used to create installation program for software packages.
In some cases, the generated programs load extension modules the name and possible locations depend on the considered package. However, in some cases, the installer looks for these extension DLL in folders which are writeable by unprivileged users, while the installation program that loads and run this DLL is expected to be run by an administrator. A typical case of this is the download folder of a browser. One should note that these installers are expected to be run only a few times, so possibilities of exploit attempts are rare.
This bug has also been reported for other products in the bulletin VIGILANCE-VUL-18671.
An attacker can therefore create a malicious DLL for Flexera InstallShield or JRSoft Inno Setup, in order to run code with administrator privileges.

Description of the vulnerability
The bulletin VIGILANCE-VUL-15399 describes a vulnerability of bash.
However, the offered patch (VIGILANCE-SOL-36695) is incomplete. An variant of the initial attack can thus still be used to execute code or to create a file.
In this case, the code is run when the variable is parsed (which is not necessarily an environment variable), and not when the shell starts. The impact may thus be lower, but this was not confirmed.
An attacker can therefore define a special environment variable, which is transmitted (via CGI or OpenSSH for example) to bash, in order to execute code.
