Synopsis ========
Poppler is vulnerable to an integer overflow and a stack overflow.
Background ==========
Poppler is a cross-platform PDF rendering library originally based on Xpdf.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/poppler < 0.5.4-r2 >= 0.5.4-r2
Description ===========
Poppler and Xpdf are vulnerable to an integer overflow in the StreamPredictor::StreamPredictor function, and a stack overflow in the StreamPredictor::getNextLine function. The original vulnerability was discovered by Maurycy Prodeus. Note: Gentoo's version of Xpdf is patched to use the Poppler library, so the update to Poppler will also fix Xpdf.
Impact ======
By enticing a user to view a specially crafted program with a Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview, or Evince, a remote 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 Poppler users should upgrade to the latest version of Poppler:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/poppler-0.5.4-r2"
