Slackware Security[slackware-security] expat (SSA:2026-077-01)
New expat packages are available for Slackware 15.0 and -current to
fix security issues.
Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/expat-2.7.5-i586-1_slack15.0.txz: Upgraded.
This update fixes security issues:
Fix NULL function pointer dereference for empty external parameter entities;
it takes use of both functions XML_ExternalEntityParserCreate and
XML_SetParamEntityParsing for an application to be vulnerable.
Protect from XML_TOK_INSTANCE_START infinite loop in function
entityValueProcessor; it takes use of both functions
XML_ExternalEntityParserCreate and XML_SetParamEntityParsing for an
application to be vulnerable.
Fix NULL dereference in function setContext on retry after an earlier
ouf-of-memory condition; it takes use of function XML_ParserCreateNS or
XML_ParserCreate_MM for an application to be vulnerable.
