Several vulnerabilities were discovered in t1lib, a Postscript Type 1 font rasterizer library, some of which might lead to code execution through the opening of files embedding bad fonts. CVE-2010-2642 A heap-based buffer overflow in the AFM font metrics parser potentially leads to the execution of arbitrary code. CVE-2011-0433 Another heap-based buffer overflow in the AFM font metrics parser potentially leads to the execution of arbitrary code. CVE-2011-0764 An invalid pointer dereference allows execution of arbitrary code using crafted Type 1 fonts. CVE-2011-1552 Another invalid pointer dereference results in an application crash, triggered by crafted Type 1 fonts. CVE-2011-1553 A use-after-free vulnerability results in an application crash, triggered by crafted Type 1 fonts. CVE-2011-1554 An off-by-one error results in an invalid memory read and application crash, triggered by crafted Type 1 fonts. For the oldstable distribution (lenny), this problem has been fixed in version 5.1.2-3+lenny1. For the stable distribution (squeeze), this problem has been fixed in version 5.1.2-3+squeeze1. For the testing distribution (wheezy), this problem has been fixed in version 5.1.2-3.4. For the unstable distribution (sid), this problem has been fixed in version 5.1.2-3.4. We recommend that you upgrade your t1lib packages.
