Background ========== Xpdf is a PDF file viewer that runs under the X Window System. Poppler is a PDF rendering library based on the Xpdf 3.0 code base. GPdf is a PDF file viewer for the GNOME 2 platform, also based on Xpdf. libextractor is a library which includes Xpdf code to extract arbitrary meta-data from files. pdftohtml is a utility to convert PDF files to HTML or XML formats that makes use of Xpdf code to decode PDF files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf < 3.01-r5 >= 3.01-r5 2 app-text/poppler < 0.4.3-r4 >= 0.4.3-r4 3 app-text/gpdf < 2.10.0-r3 >= 2.10.0-r3 4 media-libs/libextractor < 0.5.9 >= 0.5.9 5 app-text/pdftohtml < 0.36-r4 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers. ------------------------------------------------------------------- 5 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Chris Evans has reported some integer overflows in Xpdf when attempting to calculate buffer sizes for memory allocation, leading to a heap overflow and a potential infinite loop when handling malformed input files. Impact ====== By sending a specially crafted PDF file to a victim, an attacker could cause an overflow, potentially resulting in the execution of arbitrary code with the privileges of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All Xpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.01-r5" All Poppler users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/poppler-0.4.3-r4" All GPdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.10.0-r3" All libextractor users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libextractor-0.5.9" All pdftohtml users should migrate to the latest stable version of Poppler.
