EulerOS 2.0 SP3 : pidgin (EulerOS-SA-2019-2650)

high Nessus Plugin ID 132185

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the pidgin package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - A buffer overflow 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 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 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)

 - 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 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)

 - 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 user can send an invalid mood to trigger this vulnerability.(CVE-2016-2373)

 - 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 NULL pointer dereference vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent via the server could potentially result in a denial of service vulnerability. A malicious server can send a packet starting with a NULL byte triggering the vulnerability.(CVE-2016-2369)

 - An exploitable memory corruption vulnerability exists in the handling of the MXIT protocol in Pidgin.
 Specially crafted MXIT MultiMX message sent via the server can result in an out-of-bounds write leading to memory disclosure and code execution.(CVE-2016-2374)

 - An exploitable out-of-bounds read exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT contact information sent from the server can result in memory disclosure.(CVE-2016-2375)

 - 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)

 - 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 attacker can send an invalid size for a file transfer 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 file is sent to another user.(CVE-2016-2372)

 - 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)

 - An out-of-bounds write vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent via the server could cause memory corruption resulting in code execution.(CVE-2016-2371)

 - Multiple memory corruption vulnerabilities exist in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent via the server could result in multiple buffer overflows, potentially resulting in code execution or memory disclosure.(CVE-2016-2368)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected pidgin packages.
