Slackware Security[slackware-security] expat (SSA:2026-223-01)
New expat packages are available for Slackware 15.0 and -current to
fix a security issue.
Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/expat-2.7.5-i586-3_slack15.0.txz: Rebuilt.
This update fixes a security issue:
Fix an out-of-bounds read and the resulting infinite loop caused by treating
low surrogates (Unicode) the same as high surrogates in functions *_toUtf16.
