Detail
| Problem Description: Updated pango packages that fix one security issue are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: Pango is a library used for the layout and rendering of internationalized text. It was discovered that Pango did not check for memory reallocation failures in the hb_buffer_ensure() function. An attacker able to trigger a reallocation failure by passing sufficiently large input to an application using Pango could use this flaw to crash the application or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-0064) Red Hat would like to thank the Mozilla Security Team for reporting this issue. All pango users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, you must restart your system or restart the X server for the update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 678563 - CVE-2011-0064 pango: missing memory reallocation failure checking in hb_buffer_ensure |

| Title: | USN-1082-1 -- pango1.0 vulnerabilities | ||
| Description: | Marc Schoenefeld discovered that Pango incorrectly handled certain Glyph Definition tables. If a user were tricked into displaying text with a specially-crafted font, an attacker could cause Pango to crash, resulting in a denial of service. This issue only affected Ubuntu 8.04 LTS and 9.10. Dan Rosenberg discovered that Pango incorrectly handled certain FT_Bitmap objects. If a user were tricked into displaying text with a specially- crafted font, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. The default compiler options for affected releases should reduce the vulnerability to a denial of service. It was discovered that Pango incorrectly handled certain memory reallocation failures. If a user were tricked into displaying text in a way that would cause a reallocation failure, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. This issue only affected Ubuntu 9.10, 10.04 LTS and 10.10 | ||

| 71247 | Pango pango/opentype/hb-buffer.c hb_buffer_ensure() Memory Corruption A memory corruption flaw exists in Pango. The 'hb_buffer_ensure()' function in 'pango/opentype/hb-buffer.c' fails to properly check the return value of memory reallocation operations, resulting in memory corruption. With specially crafted OpenType font data, a context-dependent attacker can execute arbitrary code. |
