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.
