Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2024:0119-1 advisory.

- Tinyproxy 1.8.3 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption) via (1) a large number of headers or (2) a large number of forged headers that trigger hash collisions predictably. bucket. (CVE-2012-3505)

- main.c in Tinyproxy 1.8.4 and earlier creates a /run/tinyproxy/tinyproxy.pid file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for tinyproxy.pid modification before a root script executes a kill `cat /run/tinyproxy/tinyproxy.pid` command. (CVE-2017-11747)

- Potential leak of left-over heap data if custom error page templates containing special non-standard variables are used. Tinyproxy commit 84f203f and earlier use uninitialized buffers in process_request() function. (CVE-2022-40468)

- Rejected reason: This CVE ID is a duplicate of CVE-2022-40468 (CVE-2023-40533)

- A use-after-free vulnerability exists in the HTTP Connection Headers parsing in Tinyproxy 1.11.1 and Tinyproxy 1.10.0. A specially crafted HTTP header can trigger reuse of previously freed memory, which leads to memory corruption and could lead to remote code execution. An attacker needs to make an unauthenticated HTTP request to trigger this vulnerability. (CVE-2023-49606)

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

Solution

Update the affected tinyproxy package.
