Synopsis

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

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2915 advisory.

- ConnMan (aka Connection Manager) 1.30 through 1.39 has a stack-based buffer overflow in uncompress in dnsproxy.c via NAME, RDATA, or RDLENGTH (for A or AAAA). (CVE-2021-33833)

- 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)

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

Solution

Upgrade the connman packages.

For Debian 9 stretch, these problems have been fixed in version 1.33-3+deb9u3.
