Artifex » Afpl Ghostscript : Security Vulnerabilities, CVEs, CVSS score >= 4

Multiple use-after-free vulnerabilities in the gx_image_enum_begin function in base/gxipixel.c in Ghostscript before ecceafe3abba2714ef9b432035fe0739d9b1a283 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PostScript document.

Integer overflow in the gs_heap_alloc_bytes function in base/gsmalloc.c in Ghostscript 9.15 and earlier allows remote attackers to cause a denial of service (crash) via a crafted Postscript (ps) file, as demonstrated by using the ps2pdf command, which triggers an out-of-bounds read or write.

The getenv and filenameforall functions in Ghostscript 9.10 ignore the "-dSAFER" argument, which allows remote attackers to read data via a crafted postscript file.

The gs_type2_interpret function in Ghostscript allows remote attackers to cause a denial of service (incorrect pointer dereference and application crash) via crafted font data in a compressed data stream, aka bug 691043.

Ghostscript 8.71 and earlier reads initialization files from the current working directory, which allows local users to execute arbitrary PostScript commands via a Trojan horse file, related to improper support for the -P- option to the gs program, as demonstrated using gs_init.ps, a different vulnerability than CVE-2010-4820.

Buffer overflow in gs/psi/iscan.c in Ghostscript 8.64 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted PDF document containing a long name.

Off-by-one error in the Ins_MINDEX function in the TrueType bytecode interpreter in Ghostscript before 8.71 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a malformed TrueType font in a document that trigger an integer overflow and a heap-based buffer overflow.
