Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously.
security fix(es): 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) a denial of service vulnerability exists in the handling of the mxit protocol in pidgin.
Specially crafted mxit data sent from the server could potentially result in an out-of-bounds read.
A malicious server or man-in-the-middle attacker can send invalid data to trigger this vulnerability.(cve-2016-2370) 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 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.
Specially crafted mxit data sent via the server could potentially result in a denial of service vulnerability.
