CVE-2007-1880 in Kaspersky
Summary
by MITRE
Integer overflow in the _NtSetValueKey function in klif.sys in Kaspersky Anti-Virus, Anti-Virus for Workstations, Anti-Virus for File Server 6.0, and Internet Security 6.0 before Maintenance Pack 2 build 6.0.2.614 allows context-dependent attackers to execute arbitrary code via a large, unsigned "data size argument," which results in a heap overflow.

The vulnerability described in CVE-2007-1880 represents a critical integer overflow condition within the kernel-level driver component of Kaspersky security software products. This flaw exists specifically within the _NtSetValueKey function of the klif.sys driver, which serves as a core component in Kaspersky's antivirus and internet security solutions. The vulnerability affects multiple product variants including Anti-Virus for Workstations, Anti-Virus for File Server, and Internet Security versions 6.0 prior to Maintenance Pack 2 build 6.0.2.614, making it a widespread issue across Kaspersky's security portfolio.
The technical nature of this vulnerability stems from improper input validation within the kernel driver where unsigned data size arguments are processed without adequate bounds checking. When attackers provide a large unsigned value for the data size parameter, the integer overflow occurs during arithmetic operations, leading to a heap-based buffer overflow condition. This heap overflow creates a situation where attacker-controlled data can overwrite adjacent memory locations, potentially allowing for arbitrary code execution with kernel-level privileges. The vulnerability is context-dependent, meaning that successful exploitation requires specific conditions related to how the vulnerable function is invoked and the nature of the input data provided.
The operational impact of this vulnerability is severe, as it allows remote attackers to achieve privilege escalation from user-level to kernel-level execution. This represents a significant security risk since kernel-level code execution provides complete system compromise capabilities, enabling attackers to bypass all security controls, install persistent backdoors, and access sensitive system resources. The vulnerability affects systems running affected Kaspersky products, potentially compromising enterprise networks where these security solutions are deployed. The heap overflow condition specifically targets memory allocation patterns within the kernel driver, making it particularly dangerous as it can lead to system crashes, data corruption, or complete system takeover.
Mitigation strategies for this vulnerability should focus on immediate patch deployment as provided by Kaspersky through Maintenance Pack 2 for the affected versions. System administrators should prioritize updating all affected Kaspersky products to the patched versions that address the integer overflow condition in the klif.sys driver. Additionally, network segmentation and access controls should be implemented to limit potential attack vectors, while monitoring systems should be configured to detect anomalous behavior patterns that might indicate exploitation attempts. From a cybersecurity perspective, this vulnerability aligns with CWE-190, which describes integer overflow conditions, and represents a typical example of how kernel-level vulnerabilities can be exploited to achieve privilege escalation as outlined in ATT&CK technique T1068. Organizations should also consider implementing runtime application protection measures and memory corruption detection mechanisms as additional defensive layers. The vulnerability demonstrates the importance of thorough input validation in kernel-mode drivers and highlights the critical need for robust security testing of system-level components that handle user-supplied data.
