  "details": "In Xpdf 4.02, SplashOutputDev::endType3Char(GfxState *state)\nSplashOutputDev.cc:3079 is trying to use the freed `t3GlyphStack->cache`, which\ncauses an `heap-use-after-free` problem. The codes of a previous fix for nested\nType 3 characters wasn't correctly handling the case where a Type 3 char\nreferred to another char in the same Type 3 font (CVE-2020-25725).\n\nXpdf 4.02 allows stack consumption because of an incorrect subroutine reference\nin a Type 1C font charstring, related to the FoFiType1C::getOp() function\n(CVE-2020-35376).\n",
