www/varnish-libvmod-digest -- base64 decoding vulnerability

2025-12-12 · CVE-2023-41104 · VuXML entry

varnish developers report: Common usage of vmod-digest is for basic HTTP authentication, in which case it may be possible for an attacker to circumvent the authentication check. If the decoded result string is somehow being made visible to the attacker (for example the result of the decoding is added to a response header), then there is the potential for information disclosure from reading out of band workspace data.

Affected versions

• varnish-libvmod-digest < 1.0.3

By system

1 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
