Detail
| A vulnerability has been found and corrected in pango: It was discovered that pango did not check for memory reallocation failures in hb_buffer_ensure() function. This could trigger a NULL pointer dereference in hb_buffer_add_glyph(), where possibly untrusted input is used as an index used for accessing members of the incorrectly reallocated array, resulting in the use of NULL address as the base array address. This can result in application crash or, possibly, code execution (CVE-2011-1002). The updated packages have been patched to correct this issue. |

| 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 | ||

| Id | Description |
|---|---|
| 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. |
| 70948 | Avahi avahi-core/socket.c Empty UDP Packet Remote DoS Avahi contains a flaw that may allow a remote denial of service. The issue is triggered when 'avahi-core/socket.c' in 'avahi-daemon' fails to properly handle empty IPv4 or IPv6 UDP packets sent to port 5353, allowing a remote attacker to cause an infinite loop which will trigger a denial of service. |
