Date: Tue, 13 Jul 2010 23:34:47 +0200 From: Robert Święcki <robert@...ecki.net> To: oss-security@...ts.openwall.com Subject: Multiple bugs in freetype FYI I've reported recently multiple problems in freetype (around ~20), most of them are NULL-ptr derefs, stack exhaustion and div by zero issues, but the rest might be interesting. RedHat was kind enough to assign CVE numbers to some of them. vendor-sec members tend to treat it as public issues, so reposting here: > CVE-2010-2497 freetype integer underflow #30082 #30083 > CVE-2010-2498 freetype invalid free #30106 > CVE-2010-2499 freetype buffer overflow #30248 #30249 > CVE-2010-2500 freetype integer overflow #30263 > CVE-2010-2519 freetype heap buffer overflow #30306 > CVE-2010-2520 freetype buffer overflow on heap #30361 I wasn't trying to make weaponized exploits, although some of those issues are clearly exploitable.
