Description SMASH SMASH 2024-01-29 09:17:28 UTC 
UTF32Encoding.cpp in POCO has a Poco::UTF32Encoding integer overflow and resultant stack buffer overflow because Poco::UTF32Encoding::convert() and Poco::UTF32::queryConvert() may return a negative integer if a UTF-32 byte sequence evaluates to a value of 0x80000000 or higher. This is fixed in 1.11.8p2, 1.12.5p2, and 1.13.0.

Factory and Backports codestreams affected.
Comment 2 Michael Vetter 2024-03-12 15:52:53 UTC 
Factory has newer version. I believe Leap needs a fix.
Assigning to new maintainer.
