Description

The remote host is affected by the vulnerability described in GLSA-202405-18 (Xpdf: Multiple Vulnerabilities)

 - In Xpdf 4.02, SplashOutputDev::endType3Char(GfxState *state) SplashOutputDev.cc:3079 is trying to use the freed `t3GlyphStack->cache`, which causes an `heap-use-after-free` problem. The codes of a previous fix for nested Type 3 characters wasn't correctly handling the case where a Type 3 char referred to another char in the same Type 3 font. (CVE-2020-25725)

 - Xpdf 4.02 allows stack consumption because of an incorrect subroutine reference in a Type 1C font charstring, related to the FoFiType1C::getOp() function. (CVE-2020-35376)

 - There is a Null Pointer Dereference vulnerability in the XFAScanner::scanNode() function in XFAScanner.cc in xpdf 4.03. (CVE-2021-27548)

 - In Xpdf prior to 4.04, the DCT (JPEG) decoder was incorrectly allowing the 'interleaved' flag to be changed after the first scan of the image, leading to an unknown integer-related vulnerability in Stream.cc. (CVE-2022-24106)

 - Xpdf prior to 4.04 lacked an integer overflow check in JPXStream.cc. (CVE-2022-24107)

 - xpdf 4.03 has heap buffer overflow in the function readXRefTable located in XRef.cc. An attacker can exploit this bug to cause a Denial of Service (Segmentation fault) or other unspecified effects by sending a crafted PDF file to the pdftoppm binary. (CVE-2022-27135)

 - Xpdf prior to version 4.04 contains an integer overflow in the JBIG2 decoder (JBIG2Stream::readTextRegionSeg() in JBIG2Stream.cc). Processing a specially crafted PDF file or JBIG2 image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability described by CVE-2021-30860 (Apple CoreGraphics). (CVE-2022-38171)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

All Xpdf users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=app-text/xpdf-4.04
