An update for pidgin is now available for HCE 1.1 Security Advisory hws_security@huawei.com Huawei Cloud HCE1-SA-2023-0035 Final 1.0 1.0 2023-01-05T02:56:00:00Z current version 2023-01-05T02:56:00:00Z 2023-01-05T02:56:00:00Z HCE SA Engine 1.0.0 An update for pidgin is now available for HCE 1.1 HCE Security has rated this update as having a security impact of Critical.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section. 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) 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 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 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) 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) 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) 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) An issue was discovered in Pidgin before 2.14.9. A remote attacker who can spoof DNS responses can redirect a client connection to a malicious server. The client will perform TLS certificate verification of the malicious domain name instead of the original XMPP service domain, allowing the attacker to take over control over the XMPP connection and to obtain user credentials and all communication content. This is similar to CVE-2022-24968. (CVE-2022-26491) 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) 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 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) 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) 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 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) 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) 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) 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) Pidgin version <2.11.0 contains a vulnerability in X.509 Certificates imports specifically due to improper check of return values from gnutls_x509_crt_init() and gnutls_x509_crt_import() that can result in code execution. This attack appear to be exploitable via custom X.509 certificate from another client. This vulnerability appears to have been fixed in 2.11.0.
