  script_tag(name:"insight", value:"A buffer overflows vulnerability exists in the handling of the MXIT
protocol in Pidgin. Specially crafted MXIT data sent from the server could
potentially result in arbitrary code execution. A malicious server or an
attacker who intercepts the network traffic can send an invalid size for a
packet which will trigger a buffer overflow (CVE-2016-2376).

A buffer vulnerability exists in the handling of the MXIT protocol in
Pidgin. Specially crafted MXIT data sent by the server could potentially
result in an out of bounds write of one byte. A malicious server can send
a negative content-length in response to a HTTP request triggering the
vulnerability (CVE-2016-2377).

A buffer overflow vulnerability exists in the handling of the MXIT
protocol Pidgin. Specially crafted data sent via the server could
potentially result in a buffer overflow, potentially resulting in memory
corruption. A malicious server or an unfiltered malicious user can send
negative length values to trigger this vulnerability (CVE-2016-2378).

An information leak exists in the handling of the MXIT protocol in Pidgin.
Specially crafted MXIT data sent to the server could potentially result in
an out of bounds read. A user could be convinced to enter a particular
string which would then get converted incorrectly and could lead to a
potential out-of-bounds read (CVE-2016-2380).

A directory traversal exists in the handling of the MXIT protocol in
Pidgin. Specially crafted MXIT data sent from the server could potentially
result in an overwrite of files. A malicious server or someone with access
to the network traffic can provide an invalid filename for a splash image
triggering the vulnerability (CVE-2016-4323).

A denial of service vulnerability exists in the handling of the MXIT
protocol in Pidgin. Specially crafted MXIT data sent via the server could
potentially result in a null pointer dereference. A malicious server or an
attacker who intercepts the network traffic can send invalid data to
trigger this vulnerability and cause a crash (CVE-2016-2365).

A denial of service vulnerability exists in the handling of the MXIT
protocol in Pidgin. Specially crafted MXIT data sent via the server could
potentially result in an out-of-bounds read. A malicious server or an
attacker who intercepts the network traffic can send invalid data to
trigger this vulnerability and cause a crash (CVE-2016-2366).

An information leak exists in the handling of the MXIT protocol in Pidgin.
Specially crafted MXIT data sent via the server could potentially result
in an out of bounds read. A malicious user, server, or man-in-the-middle
can send an invalid size for an avatar which will trigger an out-of-bounds
read vulnerability. This could result in a denial of service or copy data
from memory to the file, resulting in an information leak if the avatar is
sent to another user (CVE-2016-2367).
