Уязвимость модуля mod_wstunnel веб-сервера lighttpd, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость модулей mod_fastcgi и mod_scgi веб-сервера lighttpd, позволяющая нарушителю вызвать отказ в обслуживании

In lighttpd 1.4.65, mod_wstunnel does not initialize a handler function pointer if an invalid HTTP request (websocket handshake) is received. It leads to null pointer dereference which crashes the server. It could be used by an external attacker to cause denial of service condition.

A resource leak in gw_backend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service (connection-slot exhaustion) after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of mod_fastcgi is, for example, affected. This is fixed in 1.4.67.

Уязвимость браузеров Mozilla Firefox, Mozilla Firefox ESR и почтового клиента Thunderbird, связанная с выходом операции за границы буфера в памяти в процессе некорректного программного рендеринга видео с кодировкой H.264, позволяющая нарушителю выполнить атаку типа «отказ в обслуживании» (DoS)

An out-of-bounds read can occur when decoding H264 video. This results in a potentially exploitable crash. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

When injecting an HTML base element, some requests would ignore the CSP's base-uri settings and accept the injected element's base instead. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

Inconsistent data in instruction and data cache when creating wasm code could lead to a potentially exploitable crash.
*This bug only affects Firefox on ARM64 platforms.*. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

By injecting a cookie with certain special characters, an attacker on a shared subdomain which is not a secure context could set and thus overwrite cookies from a secure context, leading to session fixation and other attacks. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

During iframe navigation, certain pages did not have their FeaturePolicy fully initialized leading to a bypass that leaked device permissions into untrusted subdocuments. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

Concurrent use of the URL parser with non-UTF-8 data was not thread-safe. This could lead to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

During startup, a graphics driver with an unexpected name could lead to a stack-buffer overflow causing a potentially exploitable crash.
*This issue only affects Firefox for Android. Other operating systems are not affected.*. This vulnerability affects Firefox < 105.

Mozilla developers Nika Layzell, Timothy Nikkel, Sebastian Hengst, Andreas Pehrson, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 104 and Firefox ESR 102.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

A missing check related to tex units could have led to a use-after-free and potentially exploitable crash.
*Note*: This advisory was added on December 13th, 2022 after we better understood the impact of the issue. The fix was included in the original release of Firefox 105. This vulnerability affects Firefox ESR < 102.6, Firefox < 105, and Thunderbird < 102.6.

JPEGOPTIM v1.4.7 was discovered to contain a segmentation violation which is caused by a READ memory access at jpegoptim.c.

An issue was discovered in Gajim through 1.4.7. The vulnerability allows attackers, via crafted XML stanzas, to correct messages that were not sent by them. The attacker needs to be part of the group chat or single chat. The fixed version is 1.5.0.
