cups-browsed in cups-filters before 1.0.53 allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging a malformed cups-browsed.conf BrowseAllow directive that is interpreted as granting browse access to all IP addresses.
The processbrowsedata function in utils/cups-browsed.c in cups-browsed in cups-filters before 1.0.53 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted packet data.
The generatelocalqueue function in utils/cups-browsed.c in cups-browsed in cups-filters before 1.0.53 allows remote IPP printers to execute arbitrary commands via shell metacharacters in the host name. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2707.
cups-browsed in cups-filters 1.0.41 before 1.0.51 allows remote IPP printers to execute arbitrary commands via shell metacharacters in the (1) model or (2) PDL, related to "System V interface scripts generated for queues."
It was found that the OPVPWrapper::loadDriver() function in the pdftoopvp filter did not restrict the directory drivers could be loaded from. As the driver name can be configured based on a PPD file, processing a PDF in an attacker-controlled directory containing a malicious driver could lead to arbitrary code execution with the privileges of the "lp" user.

Multiple integer overflows in (1) OPVPOutputDev.cxx and (2) oprs/OPVPSplash.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allow remote attackers to execute arbitrary code via a crafted PDF file, which triggers a heap-based buffer overflow.
A heap-based buffer overflow flaw was found in the pdftoopvp filter. If a malicious PDF file were processed, it could lead to arbitrary code execution with the privileges of the "lp" user. This issue was due to the following fix not being present in pdftoopvp:

Multiple heap-based buffer overflows in the urftopdf filter in cups-filters 1.0.25 before 1.0.47 allow remote attackers to execute arbitrary code via a large (1) page or (2) line in a URF file.
