Issue/Introduction

Below the list of 2 vulnerabilities reported with on the Curl lib shipped with Siteminder 

 

1. CVE-2023-38545: SOCKS5 heap buffer overflow Score: High

https://curl.se/docs/CVE-2023-38545.html
Issue: The options that cause the SOCKS5 proxy with a pass of remote hostname.

This flaw makes curl overflow a heap-based buffer in the SOCKS5 proxy handshake.
When curl is asked to pass along the hostname to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself,
the maximum length that hostname can be is 255 bytes.If the hostname is detected to be longer than 255 bytes, curl switches to local name
resolving and instead passes on the resolved address only to the proxy. Due to a bug, the local variable that means "let the host resolve the name" could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too-long hostname to the target buffer instead of copying just the resolved address there.

2. CVE-2023-38546: cookie injection with no file      Score: Low

https://curl.se/docs/CVE-2023-38546.html

Issue: libcurl provides a function call that duplicates an easy handle called curl_easy_duphadle which is caused by duplicating the handle if the cookie is passed. 

Resolution

CVE-2023-38545 is not applicable to SiteMinder as it does not use PROXY functionality with libcurl.
CVE-2023-38546 is not applicable because we do not use the function that is responsible for the vulnerability.

If the above CVEs are flagged on your system by vulnerability scans please notify your security team that the Siteminder products are not susceptible.
