Dear all\,

the following crash was found by a modified version of the kAFL fuzzer (https://github.com/RUB-SysSec/kAFL).

I have attached the crashing input and an ASAN output. To reproduce the crash issue\, execute perl5 with the crashing input as script (perl \<crashing_input>).

Best regards\, Simon Wörner

This is a bug report for perl from simon.woerner@​rub.de\, generated with the help of perlbug 1.40 running under perl 5.26.1.

----------------------------------------------------------------- [Please describe your issue here] Dear all\,

the following crash was found by a modified version of the kAFL fuzzer (https://github.com/RUB-SysSec/kAFL).

I have attached the crashing input and an ASAN output. To reproduce the crash issue\, execute perl5 with the crashing input as script (perl \<crashing_input>).

Credits​: Simon Wörner\, Sergej Schumilo\, Cornelius Aschermann (all of Ruhr-Universität Bochum)

Best regards\, Simon Wörner

Running on a threaded\, debugging Perl built at blead (v5.29.2-41-ge47f50f38f) and with this input (as seen in vim)​:

##### A^@​^@​A$A.=*^@​A=@​^@​5=*A*A #####

... I got this result​:

##### Operator or semicolon missing before *A at /home/jkeenan/learn/perl/p5p/133363-crash/133363-perl_crash line 1. Ambiguous use of * resolved as operator * at /home/jkeenan/learn/perl/p5p/133363-crash/133363-perl_crash line 1. Segmentation fault (core dumped) #####

I believe that confirms the report.

Thank you very much.

The RT System itself - Status changed from 'new' to 'open'

This looks like a stack not refcounted issue, it deparses to:

'A'->A($A .= *A = @5 = *A * 'A');

The $A would be pushed, then *A is set to 0 (scalar @5) which frees $A, which .= (pp_concat) then tries to modify.
