There is an integer overflow in dav1d when decoding an AV1 video with large width/height. The integer overflow may result in an out-of-bounds write.
258b775b05e2d4378551ee4e66e5c90a5df4e7d9ef5dc5c37abec0ba66db8a8emacOS suffers from an out-of-bounds write vulnerability in AppleVADriver when decoding mpeg2 videos.
a755a34876f36a8a24fb4024eeda524426d61439be93ad37d2aa3f187ed43ce5On Intel macOS, HEVC video decoding is performed in the AppleGVA module. Using fuzzing, researchers identified multiple issues in this decoder. The issues range from out-of-bounds writes, out-of-bounds reads and, in one case, free() on an invalid address. All of the issues were reproduced on macOS Ventura 13.6 running on a 2018 Mac mini (Intel based).

ff7c534a4bbc11dc3cd3ac7fb2571e8b2fc9cddf789fa05fff2fc30be17f2acaOn newer macOS/iOS versions, entitlements in binary signature blobs are stored in the DER format. libCoreEntitlements.dylib is the userspace library for parsing and querying such entitlements. The kernel has its own version of this library inside the AppleMobileFileIntegrity module. libCoreEntitlements exposes several functions, such as, for example, to convert entitlements to a dictionary representation (e.g. CEQueryContextToCFDictionary) or to query a specific entitlement (CEContextQuery). Unfortunately, different functions traverse the DER structure in a subtly different way, which allows one API to see one set of entitlements and another API to see a different set of entitlements.
9313c983a56ba7500d8b9861b16b1c103ae3a9454de12a836126f89cec59a1b8There is a vulnerability in Cisco Jabber that allows an attacker to send arbitrary XMPP stanzas (XMPP control messages) to another Cisco Jabber client, including XMPP stanzas that are normally sent only by the trusted server.
ed2115ba91caeae4b0245ae0141359b56fa7d27077ea7a8cb6d34c1aa2ad914cThere is an out-of-bounds write vulnerability when decoding a certain flavor of RAW image files on macOS.

b0cdd2ef0c901dd72ddd0b3fa6f8cc6fcb53635705915e5ec0c9100853c07cb3There is a vulnerability in Kik Messenger for Android that allows an attacker to send arbitrary XMPP stanzas (XMPP control messages) to another Kik client, including XMPP stanzas that are normally sent only by the Kik server. Included is a proof of concept that demonstrates sending of the stc stanza which triggers a captcha dialog and opens an arbitrary attacker-control webpage on the victim client. However, the full impact is likely larger than this, and includes any application features accessible over XMPP.
3f66b31a34e395df392668d6453b6eee4bbfd623765c95d99108116f95c8a143Tigase XMPP server suffers from a security vulnerability due to not escaping double quote character when serializing parsed XML. This can be used to smuggle (or, if you prefer, inject) an arbitrary attacker-controlled stanza in the XMPP server's output stream. A malicious client can abuse this vulnerability to send arbitrary XMPP stanzas to another client (including the control stanzas that are only meant to be sent by the server).
80c339179764f04e39876070e482957638cbcf822ccdb04b5cc72ea035585e1eThis report describes a vulnerability chain that enables a malicious user to compromise another user over Zoom chat. User interaction is not required for a successful attack. The only ability an attacker needs is to be able to send messages to the victim over Zoom chat over XMPP protocol. Initial vulnerability (labeled XMPP Stanza Smuggling) abuses parsing inconsistencies between XML parsers on Zoom's client and server in order to be able to "smuggle" arbitrary XMPP stanzas to the victim client. From there, by sending a specially crafted control stanza, the attacker can force the victim client to connect to a malicious server, thus turning this primitive into a man-in-the-middle attack. Finally, by intercepting/modifying client update requests/responses, the victim client downloads and executes a malicious update, resulting in arbitrary code execution. A client downgrade attack is utilized to bypass signature check on the update installer. This attack has been demonstrated against the latest (5.9.3) client running on Windows 64-bit, however some or all parts of the chain are likely applicable to other platforms.
