Debian DSA-5231-1 : connman - security update

critical Nessus Plugin ID 165255

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5231 advisory.

- An issue was discovered in the DNS proxy in Connman through 1.40. The TCP server reply implementation lacks a check for the presence of sufficient Header Data, leading to an out-of-bounds read.
(CVE-2022-23096)

- An issue was discovered in the DNS proxy in Connman through 1.40. forward_dns_reply mishandles a strnlen call, leading to an out-of-bounds read. (CVE-2022-23097)

- An issue was discovered in the DNS proxy in Connman through 1.40. The TCP server reply implementation has an infinite loop if no data is received. (CVE-2022-23098)

- In ConnMan through 1.41, remote attackers able to send HTTP requests to the gweb component are able to exploit a heap-based buffer overflow in received_data to execute code. (CVE-2022-32292)

- In ConnMan through 1.41, a man-in-the-middle attack against a WISPR HTTP query could be used to trigger a use-after-free in WISPR handling, leading to crashes or code execution. (CVE-2022-32293)

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

Solution

Upgrade the connman packages.

For the stable distribution (bullseye), these problems have been fixed in version 1.36-2.2+deb11u1.
