CVE-2018-16541artifexghostscript+10
EPSS score1.41%
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect free logic in pagedevice replacement to crash the interpreter.CVE-2018-16511artifexghostscript+10EPSS score1.94%
An issue was discovered in Artifex Ghostscript before 9.24. A type confusion in "ztype" could be used by remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact.CVE-2018-16540artifexghostscript+12EPSS score1.56%
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files to the builtin PDF14 converter could use a use-after-free in copydevice handling to crash the interpreter or possibly have unspecified other impact.CVE-2018-16542artifexghostscript+9EPSS score1.91%
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use insufficient interpreter stack-size checking during error handling to crash the interpreter.CVE-2018-16509artifexghostscript+14EPSS score92.50%
An issue was discovered in Artifex Ghostscript before 9.24. Incorrect "restoration of privilege" checking during handling of /invalidaccess exceptions could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction.CVE-2018-16585artifexghostscript+4EPSS score1.72%
An issue was discovered in Artifex Ghostscript before 9.24. The .setdistillerkeys PostScript command is accepted even though it is not intended for use during document processing (e.g., after the startup phase). This leads to memory corruption, allowing remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact. Note: A reputable source believes that the CVE is potentially a duplicate of CVE-2018-15910 as explained in Red Hat bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1626193)CVE-2018-16510artifexghostscript+4EPSS score1.75%
An issue was discovered in Artifex Ghostscript before 9.24. Incorrect exec stack handling in the "CS" and "SC" PDF primitives could be used by remote attackers able to supply crafted PDFs to crash the interpreter or possibly have unspecified other impact.CVE-2018-16863artifexghostscript+12EPSS score1.25%
It was found that RHSA-2018:2918 did not fully fix CVE-2018-16509. An attacker could possibly exploit another variant of the flaw and bypass the -dSAFER protection to, for example, execute arbitrary shell commands via a specially crafted PostScript document. This only affects ghostscript 9.07 as shipped with Red Hat Enterprise Linux 7.CVE-2018-16543artifexghostscript+4EPSS score1.27%
In Artifex Ghostscript before 9.24, gssetresolution and gsgetresolution allow attackers to have an unspecified impact.CVE-2018-16513artifexghostscript+6EPSS score1.50%
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the setcolor function to crash the interpreter or possibly have unspecified other impact.CVE-2018-16539artifexghostscript+10EPSS score1.44%
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use incorrect access checking in temp file handling to disclose contents of files on the system otherwise not readable.CVE-2018-16802alpineghostscript+11EPSS score2.09%
An issue was discovered in Artifex Ghostscript before 9.25. Incorrect "restoration of privilege" checking when running out of stack during exception handling could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction. This is due to an incomplete fix for CVE-2018-16509.CVE-2018-19475alpineghostscript+12EPSS score9.55%
psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because available stack space is not checked when the device remains the same.CVE-2018-19477alpineghostscript+12EPSS score3.04%
psi/zfjbig2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a JBIG2Decode type confusion.CVE-2018-19478artifexghostscript+3EPSS score1.89%
In Artifex Ghostscript before 9.26, a carefully crafted PDF file can trigger an extremely long running computation when parsing the file.CVE-2018-19134artifexghostscript+8EPSS score2.87%
In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type.CVE-2018-19409alpineghostscript+10EPSS score7.83%
An issue was discovered in Artifex Ghostscript before 9.26. LockSafetyParams is not checked correctly if another device is used.CVE-2018-19476alpineghostscript+12EPSS score3.04%
psi/zicc.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access restrictions because of a setcolorspace type confusion.CVE-2018-11645artifexghostscript+9EPSS score2.58%
psi/zfile.c in Artifex Ghostscript before 9.21rc1 permits the status command even if -dSAFER is used, which might allow remote attackers to determine the existence and size of arbitrary files, a similar issue to CVE-2016-7977.CVE-2018-17183artifexghostscript+10EPSS score1.83%
Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code.
