Debian DSA-2388-1 : t1lib - several vulnerabilities

High Nessus Plugin ID 57542

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the t1lib packages.

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.
