Debian DSA-5484-1 : librsvg - security update

medium Nessus Plugin ID 180206

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5484 advisory.

 - A directory traversal problem in the URL decoder of librsvg before 2.56.3 could be used by local or remote attackers to disclose files (on the local filesystem outside of the expected area), as demonstrated by href=.?../../../../../../../../../../etc/passwd in an xi:include element. (CVE-2023-38633)

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 librsvg packages.

For the stable distribution (bookworm), this problem has been fixed in version 2.54.7+dfsg-1~deb12u1.
