Unspecified vulnerability in the pdf.xmd module in (1) BitDefender Free Edition 10 and Antivirus Standard 10, (2) BullGuard Internet Security 8.5, and (3) Software602 Groupware Server 6.0.08.1118 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PDF file, possibly related to included compressed streams that were processed with the ASCIIHexDecode filter. NOTE: some of these details are obtained from third party information.

Cross-site scripting (XSS) vulnerability in BitDefender Internet Security 2009 allows user-assisted remote attackers to inject arbitrary web script or HTML via the filename of a virus-infected file, as demonstrated by a filename inside a (1) rar or (2) zip archive file.

Unspecified vulnerability in BitDefender allows attackers to execute arbitrary code via unspecified vectors, aka EEYEB-20071024. NOTE: as of 20071029, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.

Local Privilege Escalation via Arbitrary File Operation in Bitdefender Total Security

A local privilege escalation vulnerability in Bitdefender Total Security versions prior to 27.0.47.241 allows low-privileged attackers to elevate privileges. The issue arises from bdservicehost.exe deleting files from a user-writable directory (C:\ProgramData\Atc\Feedback) without proper symbolic link validation, enabling arbitrary file deletion. This issue is chained with a file copy operation during network events and a filter driver bypass via DLL injection to achieve arbitrary file copy and code execution as elevated user.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Bitdefender Internet Security 2018. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within emulator 0x10A in cevakrnl.xmd. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before writing to memory. An attacker can leverage this vulnerability to execute code under the context of SYSTEM. Was ZDI-CAN-5102.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Bitdefender Internet Security 2018. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within emulator 0x102 in cevakrnl.xmd. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of SYSTEM. Was ZDI-CAN-5116.

Code injection vulnerability in Bitdefender Total Security 12.0 (and earlier), Internet Security 12.0 (and earlier), and Antivirus Plus 12.0 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Bitdefender process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider DLL under Image File Execution Options in the registry; (2) the self-protection mechanism is intended to block all local processes (regardless of privileges) from modifying Image File Execution Options for these products; and (3) this mechanism can be bypassed by an attacker who temporarily renames Image File Execution Options during the attack.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Bitdefender Internet Security 2018. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within cevakrnl.xmd. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code under the context of SYSTEM. Was ZDI-CAN-5101.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Bitdefender Internet Security Internet Security 2018 prior to build 7.72918. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within pdf.xmd. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code under the context of SYSTEM. Was ZDI-CAN-4361.
