Уязвимость функции EncodeAlphaInternal() библиотеки libwebp для кодирования и декодирования изображений в формате WebP браузеров Mozilla Firefox, Firefox ESR и почтового клиента Thunderbird, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость библиотеки libwebp для кодирования и декодирования изображений в формате WebP, связанная с чтением за границами буфера в памяти, позволяющая нарушителю выполнить произвольный код

There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode() function and loop through to free best.bw and assign best = trial pointer. The second loop will then return 0 because of an Out of memory error in VP8 encoder, the pointer is still assigned to trial and the AddressSanitizer will attempt a double free.

Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical)

Уязвимость компонента xrdp_painter.c сервера XRDP, позволяющая нарушителю получить доступ к защищаемой информации

xrdp is an open source remote desktop protocol server. Access to the font glyphs in xrdp_painter.c is not bounds-checked . Since some of this data is controllable by the user, this can result in an out-of-bounds read within the xrdp executable. The vulnerability allows an out-of-bounds read within a potentially privileged process. On non-Debian platforms, xrdp tends to run as root. Potentially an out-of-bounds write can follow the out-of-bounds read. There is no denial-of-service impact, providing xrdp is running in forking mode. This issue has been addressed in release 0.9.23.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
