AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding() and AppendEncodedCharacters() could have experienced integer overflows, causing underallocation of an output buffer leading to an out of bounds write. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
Weakness
The product performs a calculation to determine how much memory to allocate, but an integer overflow can occur that causes less memory to be allocated than expected, leading to a buffer overflow.
