Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2020-8608)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within tcp_subr.c file in libslirp. A local user can pass specially crafted data to the application that is using the affected version of library, trigger memory corruption and execute arbitrary code on the system.


2) Integer overflow (CVE-ID: CVE-2020-10531)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in UnicodeString::doAppend() function in common/unistr.cpp. A remote attacker can pass specially crafted string to the application that is using the vulnerable library, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Buffer overflow (CVE-ID: CVE-2020-5208)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to multiple functions in ipmitool neglect proper checking of the data received from a remote LAN party. A remote authenticated attacker can trigger memory corruption and execute arbitrary code on the ipmitool side.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Resource management error (CVE-ID: CVE-2019-11135)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the TSX Asynchronous Abort (TAA) in Intel CPUs. The TAA condition, on some microprocessors utilizing speculative execution, may allow an authenticated user to potentially enable information disclosure via a side channel.
