| Titolo | uclouvain openjpeg 2.5.4 Integer Overflow |
|---|
| Descrizione | An integer overflow vulnerability exists in opj_pi_initialise_encode() (src/lib/openjp2/pi.c). The include_size variable is calculated through a chain of 32-bit multiplications without overflow checking. When encoding parameters satisfy:
numlayers × l_max_res × numcomps × l_max_prec > UINT32_MAX
the result is truncated, causing a smaller-than-required heap buffer allocation. Subsequent accesses to the include array exceed the allocated bounds. |
