Summary
The podman tool manages pods, container images, and containers. It is part of the libpod library, which is for applications that use container pods. Container pods is a concept in Kubernetes.
Security Fix(es):
* golang: crypto/tls: slow verification of certificate chains containing large RSA keys (CVE-2023-29409)
* golang: html/template: improper handling of HTML-like comments within script contexts (CVE-2023-39318)
* golang: html/template: improper handling of special tags within script contexts (CVE-2023-39319)
* golang: crypto/tls: panic when processing post-handshake message on QUIC connections (CVE-2023-39321)
* golang: crypto/tls: lack of a limit on buffered post-handshake (CVE-2023-39322)

Unscored —CVE-2023-29409 Public exploit
Large RSA keys can cause high CPU usage in crypto/tls
Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA…

Unscored —
Improper handling of HTML-like comments in script contexts in html/template
The html/template package does not properly handle HTML-like "" comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of <script> contexts, causing actions to be imprope…

Unscored —
Improper handling of special tags within script contexts in html/template
The html/template package does not apply the proper rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. This may cause the template parser to improperly consider script contexts to be terminated early, …
-
Unscored —
Panic when processing post-handshake message on QUIC connections in crypto/tls
Processing an incomplete post-handshake message for a QUIC connection can cause a panic.
-
Unscored —
Memory exhaustion in QUIC connection handling in crypto/tls
QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now consistently reject messages larger than 65KiB in …
