@AlexPeshkoff should it be merged or were there any reasons to postpone it? |
The only reason not to merge - our code never calls tommath functions in wrong way like negative number of digits. On the other hand - changes are absolutely safe. What do you think - do we need such fix, or may be just switch to fresh tommath version? |

For v6, I suppose we may just update our libtom-imported sources. If this needs to be backported, the suggested patch is preferred -- although I doubt this is necessary given that our usage of the library is not affected by this CVE. |

Hi Development Team,
I identified a potential integer overflow in clone functions in files in
extern/libtommathsourced from libtom/libtommath. This issue, originally reported in CVE-2023-36328, was resolved in the repository via this commit libtom/libtommath@beba892.This PR applies the corresponding patch to fix the vulnerability in this codebase.
Please review at your convenience. Thank you!
